+======Tracking and Activity Recognition Through Consensus in Distributed Camera Networks======
-__Description__
+**Supervisor**: Amir Asif
-An opportunity exists for a small number of students to build an autonomous motorboat using a RC motorboat as a base and integrating computation and control in the form of a Beagleboard. Students will participate in lectures and labs associated with CSE6324 (Part I). Interested students should attend the first lecture of CSE6324. See the departmental schedule for time and place.
+**Required Background: ** Computer Vision or Signal and Systems Course preferred; Matlab; Interest in Signal/Image Processing
+**Short Description: **Over the past decade, large-scale camera networks have become increasingly popular in a wide range of applications, including: (i) Sports analysis; (ii) Security and surveillance; (iii) disaster response, and; (iv) Environmental modeling, where the objective is to follow the trajectory of a key target, for example, a star player in a soccer game or a suspect in a surveillance environment. In many applications, bandwidth constraints, security concerns, and difficulty in storing and analyzing large amounts of image data centrally at a single location necessitate the development of distributed camera network architectures. In this project, we investigate distributed scene analysis algorithms, where each camera estimates certain parameters of the target using a signal processing algorithm based upon its own set of observations. The local estimates are then shared with the neighboring cameras in an iterative, goosip-type fashion, and a final estimate is computed across the network using consensus algorithms. The selected student will develop Matlab code to apply distributed signal processing algorithms [1,2] that have been developed in the Signal Processing and Communications lab for target tracking and activity recognition in distributed camera networks.

-__Description__
+**Supervisor**: Wolfgang Stuerzlinger
-The Athenians Project is a multi-year, ongoing project of compiling, computerizing and studying data about the persons of ancient Athens.
-Possible project ideas for this term span from simpler ones such as
-how to present data in the best possible way, add spatial characteristics to existing data,
-add multimedia data, improve text searching, etc. to more complex ideas such as filling
-missing parts for the "broken" words on the existing inscriptions. Filling text for the broken
-words has been done in the past using expert knowledge. Those experts have establish
-certain rules/guidelines that may be possible to extrapolate in some kind of expert system
-when talking in IT terminology. Furthermore, any hypotheses on word completion enters
-the database with some likelihood. Associating probabilities with hypotheses introduces
-another opportunity for research projects.

-====== Three-Dimensional Context from Linear Perspective for Video Surveillance Systems ======
+**Required Background**: 3D computer graphics, C/C++ coding
-**Supervisor**:  James Elder
+The Leap Motion, leapmotion.com, is a new device that lets users control a computer with their fingers. This project creates a new 3D drawing system that enables users to quickly generate 3D solids.
-**Requirements**:  Good facility with applied mathematics
+====== 3D Drawing System with 3Gear gesture tracker ======
-__Description__
+**Supervisor**: Wolfgang Stuerzlinger
-To provide visual surveillance over a large environment, many surveillance cameras are typically deployed at widely dispersed locations.  Making sense of activities within the monitored space requires security personnel to map multiple events observed on two-dimensional security monitors to the three-dimensional scene under surveillance.  The cognitive load entailed rises quickly as the number of cameras, complexity of the scene and amount of traffic increases.
+**Required Background**: 3D computer graphics, C/C++ coding
-This problem can be addressed by automatically pre-mapping two-dimensional surveillance video data into three-dimensional coordinates.  Rendering the data directly in three dimensions can potentially lighten the cognitive load of security personnel and make human activities more immediately interpretable.
+The 3Gear system, threegear.com, lets users control a computer with their hands and fingers. This project creates a new 3D drawing system that enables users to quickly generate and modify 3D solids.
-Mapping surveillance video to three-dimensional coordinates requires construction of a virtual model of the three-dimensional scene.  Such a model could be obtained by survey (e.g., using LIDAR), but the cost and time required for each site would severely limit deployment.  Wide-baseline uncalibrated stereo methods are developing and have potential utility, but require careful sensor placement, and the difficulty of the correspondence problem limits reliability.
-This project will investigate a monocular method for inferring three-dimensional context for video surveillance.  The method will make use of the fact that most urban scenes obey the so-called “Manhattan-world” assumption, viz., a large proportion of the major surfaces in the scene are rectangles aligned with a three-dimensional Cartesian grid (Coughlan & Yuille, 2003).  This regularity provides strong linear perspective cues that can potentially be used to automatically infer three-dimensional models of the major surfaces in the scene (up to a scale factor).  These models can then be used to construct a virtual environment in which to render models of human activities in the scene.
-Although the Manhattan world assumption provides powerful constraints, there are many technical challenges that must be overcome before a working prototype can be demonstrated.  The prototype requires six stages of processing:    1)The major lines in each video frame are detected.  2)  These lines are grouped into quadrilaterals projecting from the major surface rectangles of the scene.  3)  The geometry of linear perspective and the Manhattan world constraint are exploited to estimate the three-dimensional attitude of the rectangles from which these quadrilaterals project.  4)  Trihedral junctions are used to infer three-dimensional surface contact and ordinal depth relationships between these surfaces.  5)  The estimated surfaces are rendered in three-dimensions.  6)  Human activities are tracked and rendered within this virtual three-dimensional world.
+====== Tilt Target Selection on Touchscreen Phones ======

+**Required Background**: General 4080 prerequisites, CSE3461, and (preferably) CSE4441. Interest in user interfaces and human-computer interaction (HCI).  Students can use their own Android phone for the project or one supplied by the course supervisor.
-----
+Touchscreen mobile devices commonly use a built-in accelerometer to sense movement or tilting actions of the device.  Tilt is commonly used the change the orientation of the display between portrait and landscape.  Gaming is another common use for tilting actions.  However, tilt may also be used for target selection, as a replacement for touch.  This research project will evaluate tilt as an input primitive for target selection on touchscreen mobile devices.

+====== Attentive Sensing for Better Two-Way Communication in Remote Learning Environments ======
-**Requirements**:  Good facility with applied mathematics
+**Supervisor**: James Elder
-__Description__
+**Required Background**: General CSE408x prerequisites, good programming skills,
+good math skills, knowledge of C and MATLAB programming languages
-Facilities planning at both city (e.g., Toronto) and institutional (e.g., York University) scales requires accurate data on the flow of people and vehicles throughout the environment.  Acquiring these data can require the costly deployment of specialized equipment and people, and this effort must be renewed at regular intervals for the data to be relevant.
+One of the challenges in remote learning is to allow students to communicate effectively with the lecturer.  For example, when a student asks a question, communication will be more effective if the instructor has a zoomed view of the student’s face, so that s/he can interpret expressions etc.
-The density of permanent urban video surveillance camera installations has increased dramatically over the last several years.  These systems provide a potential source of low-cost data from which flows can be estimated for planning purposes.
+The goal of this project is to apply attentive sensing technology (www.elderlab.yorku.ca) to this problem.  This technology is able to monitor a large environment such as a classroom and direct a high-resolution ‘attentive’ sensor to events of interest.
-This project will explore the use of computer vision algorithms for the automatic estimation of pedestrian and vehicle flows from video surveillance data.  The ultimate goal is to provide planners with accurate, continuous, up-to-date information on facility usage to help guide planning.
-The student will work closely with graduate students and postdoctoral fellows at York University, as well as researchers at other institutions involved in the project.  The student will develop skills in using MATLAB, a very useful mathematical programming environment, and develop an understanding of basic topics in image processing and vision.

-====== Tandem repeat detection using spectral methods ======
-**Supervisor**: Suprakash Datta
+====== Attentive Sensing for Sport Video Recording Markets ======
-**Required Background**: The student should have completed undergraduate courses in Algorithms and Signals and Systems.
+**Supervisor**: James Elder
-**Recommended Background**: Some background in Statistics is desirable but not essential.
+**Required Background**: Good programming skills; Good math skills; Knowledge of C and MATLAB programming languages
-__Description__
-DNA sequences of organisms have many repeated substrings. These are called repeats in Biology, and include both exact as well as approximate repeats. Repeats are of two main types: interspersed repeats (which are spread across a genome) and tandem repeats, which occur next to each other. Tandem repeats play important roles in gene regulation and are also used as markers that have several important uses, including human identity testing.
+The goal of this project is to modify York University’s patented attentive sensor technology to the sport video recording market.  Specific application domains under investigation include skiing, indoor BMX parks, and horse tracks.
+The general problem is to use attentive sensing technology (www.elderlab.yorku.ca) to visually detect and track multiple moving agents (e.g., skiers, riders, horses) and to select specific agents for active high-resolution smooth pursuit.
+The student will work with senior graduate students, postdoctoral fellows and research scientists to help modify the attentive sensing technology to operate in these domains.   Specific tasks include:
+.     Ground-truth available datasets
+.     Evaluate current attentive algorithms on these datasets
+.     Modify these algorithms to improve performance on these datasets
-Finding tandem repeats is an important problem in Computational Biology. The techniques that have been proposed for it fall into two classes: string matching algorithms and signal processing techniques. In this project, we will explore fast, accurate algorithms for detecting tandem repeats and evaluate the outputs of the algorithms studied by comparing their outputs with those of available packages, including mreps (http://bioinfo.lifl.fr/mreps/), SRF (http://www.imtech.res.in/raghava/srf/) and TRF (http://tandem.bu.edu/trf/trf.html).
-The student will implement existing spectral algorithms based on Fourier Transforms and on an autoregressive model. He will then make changes suggested by the supervisor, and evaluate the effect of the modifications. Throughout the course, the student is required to maintain a course Web site to report any progress and details about the project.

-====== Touch- and Gesture-based Text Entry With Automatic Error Correction ======
-**Supervisor**: Scott Mackenzie
-**Required Background**:
-CSE3461 (or equivalent), CSE3311 (or equivalent), CSE4441 (or equivalent)
-A student wishing to do this project must be well versed in Java, Eclipse, and developing java code for the Android operating system.
-**Recommended Background**:
-Possession of an Android touch-based phone or tablet would be an asset, but is not essential.
-__Description__
-This project involves extending a touch-based text entry method to include automatic error correction.  The method, as is, uses Graffiti strokes entered via a finger on a touch-based Android tablet.  The stroke recognizer works fine, but it is not perfect.  Some strokes are mis-recognized while others are un-recognized.  The fault is sometimes attributable to the recognizer, but, often, the fault is simply that the user's input was sloppy.  The work involves developing, integrating, and testing software.  The core software is already written, but automatic error correction is lacking. The primary task of the added software is to receive a sequence of characters representing a word and matching the sequence with words in a dictionary.  If a match is found, all is well (presumably).  If a match is not found, the search is extended to find a set of candidate words that are "close" to the inputted sequence.  "Close", here, involves using a minimum string distance algorithm (provided).  The user interface must be modified to present the user with alternative words in the event an error occurred.  The user selects the desired word by tapping on a word in the list.  The project will involve testing the new input method in a small user study and writing up a report describing the work and presenting the results of the user study.

-====== Developing Fast Speech Recognition Engine using GPU ======
-**Supervisor**: Hui Jang
+To date a promising functional application has been developed in JAVA by a Computer Science student as a 4080 project. The existing software allows the user to draw a path diagram and outputs code for the R package sem.  There are a number of improvements to be made (refinements and additions to graphical user interface) and then the application needs to be extended to output syntax appropriate for additional software applications (openMX, MPlus and EQS).  Though this project may not begin at “the first stages” of the software lifecycle, this scenario is likely common in the software development market. In addition, the student will be working with a primary “client” who is far less technically advanced, which is also reflective of real-world situations.

-General prerequisites
-__Description__
-Recently, Graphics Processing Units (GPU's) have been widely used as an extremely fast computing vehicle for a variety of real-world applications. Many software programs have been developed for GPU's to take advantage of its multi-core parallel computing architecture (see gpgpu.org). In the past few years, we have developed a state-of-the-art speech recognition engine using anti-C at York and it runs very well in a normal CPU-based platform. In this project, you are required to port this engine (the C source code is available) based on the standard CUDA or OpenCL library to make it run in GPU's. It has been reported that this may lead to a speedup of at least 10 times faster in many speech recognition tasks [1][2].
+====== Enabling SaaS access to an experimental AI planner ======
-During the recent years, there is an increasing demand in the job market for programmers who can use GPU's for general purpose computing tasks. This project will serve as a perfect vehicle for you to learn such a cutting-edge programming skill.

+====== Calibration of a Tracked Pointer ======
-**Required Background**:
+**Supervisor**: Burton Ma
-Some knowledge of microprocessor architecture and assembly programming
-__Description__
+**Description**: Tracked pointers are the most common tools used in surgical
+navigation systems. A typical pointer has a tracked target on one
+end and a sharp or ball tip on the other end. Finding the location
+of the tip relative to the target is a calibration problem. One
+solution to the calibration problem involves pivoting the pointer
+about the tip while tracking the target; if the tip is kept
+stationary, then the target moves on the surface of a sphere.
+Fitting the tracking data to the surface of a sphere yields the
+location of the tip as the sphere center. Unfortunately, the
+calibrated tip position obtained using such a spherical calibration
+has high variance. This project will investigate how much variance
+there is in the calibrated tip position, and methods for reducing
+the variance of the calibrated tip position.

-======Web Crawlers Behaving Like Humans: Are We There Yet!? ======
-**Supervisor**: Natalija Vlajic
-**Required Background**: General prerequisites
-__Description__
-Distributed Denial of Service (DDoS) attacks are recognized as one
-of the most serious threats to today's Internet due to the relative
-simplicity of their execution and their ability to severely degrade
-the quality at which Web-based services are offered to the end users.
-An especially challenging form of DDoS attacks are the so-called
-Application-Layer DDoS attacks. Namely:
-) In Application-Layer DDoS attacks, the attackers utilize a flood
-of legitimate-looking Layer-7 network sessions (i.e., sessions that
-are generally hard to detect and/or filter out by a firewall or an
-IDS system);
-) Increasingly, these sessions comprise HTML requests generated by a
-cleverly programmed crawler that executes a semi-random walk over the
-web site links, thereby attempting to appear as a legitimate human
-visitor.
-The goal of this project is to investigate the state of the art in
-malicious web crawler design. In particular, the project will look
-into the challenges of designing a smart-DDoS-crawler from the
-attacker point of view - one of these challenges being the estimation
-of web-page popularity assuming no a priori access to the web-logs
-of the victim web-site.

-Network analysis of EEG data: Understanding connections in the brain
-====== Network analysis of EEG data: Understanding connections in the brain ======
-**Supervisor**: Andrew Eckford
-**Required Background**: CSE 3213 (Computer Networks), CSE 3451 (Signals and Systems), and MATH 2030 (Elementary Probability); or equivalents
-**Preferred**: At least a B in all of the above courses
-__Description__
-Electroencephalogram (EEG) data indicates electrical activity at particular locations in the brain. Using EEG data from multiple sensors, it is possible to find correlations among the measurements, and identify “networks” of activity in the brain. These networks help researchers to determine exactly how the brain processes various stimuli.
-The tools that are used to analyze communication networks can also be used to analyze brain networks. In this interdisciplinary project, you will work with a collection of EEG data to identify correlated measurements, and determine network-type relationships based on those measurements. To do so, you will apply skills you learned in courses on Signals and Systems, Computer Networks, and Probability. Your work may lead to a research publication.

-====== YUsend Thermal Vacuum (TVAC) Test Manager  ======
-**Supervisor**: Rob Allison (co-supervised with Hugh Chesser, Space Engineering)
-**Required Background**: General CSE408x prerequisites, familiarity with C++ and Windows software tools
-__Description__
-The YUsend (York University Space Engineering Nanosatellite Demonstration) Lab has procured a Windows XP-based industrial computer and temperature acquisition card (as well as other hardware) for performing TVAC testing of nanosatellites in the CSIL Lab (PSE 003).  A "TVAC Test Manager" application written using LabView's G programming language will oversee the acquisition of temperatures (thermal test outputs) and control of IR lamps (thermal test inputs) during the rather long periods (4 or more days, 24 hours a day) of a TVAC test.
-Specific tasks include:
-.  Writing temperature acquisition card (OMEGA Engineering CIO-DAS-Temp) drivers for LabView - should be written in Visual C++ or similar and compiled into SubVI format.
-.  Write LabView VI's ("Virtual Instrument") to perform (a) Test set-up activities - checkout of sensor and lamps, assigning neumonics to temperature sensors, setting of alarm conditions for sensors and lamps (b) Acquire and monitor temperature data and control lamp voltage during test, raise operator alarms for temperature or IR lamp anomalous conditions as required (c) Store temperature and control data for subsequent analysis and reporting.
-. (Optional) Interface the Test Manager with an orbital simulation tool which would be used to compute IR lamp inputs based on a simulation of the nanosatellite's orbital position and attitude (eg - in the sun, lamps on, in eclipse lamps off).  The simulation tool is a package called Satellite Toolkit (STK) which has an TCP/IP-based API.
