-**Supervisor**: Franck van Breugel
+====== Simulation for Forest Fire Detection ======
-**Required background**: General prerequisites

 __Description__
-CUDA stands for "compute unified device architecture."  It is an architecture to program multicore graphical processing units (GPUs for short).  In the past, these GPUs were only used for graphics. However, CUDA allows us to use these GPUs for other types of computation. Since today's GPUs have hundreds of cores, algorithms can be parallelized and, hence, run often much faster.
+Detection of forest fires is a challenging activity that requires considerable training. The objective of this project is to implement a virtual reality simulation to incorporate key aspects of this task and then to perform an evaluation with a small user study.
-The aim of this project is to get familiar with GPUs and to study how to program them.

+**Recommended Background**: CSE3431 or CSE4471 or equivalent
 __Description__
-The URL for Algorithmics Animation Workshop (AAW) is http://www.cs.yorku.ca/~aaw.  The main purpose of AAW is to be a pedagogical tool by providing animation of important algorithms and data structures in computer science, especially those studied in courses CSE 3101, 4101, 5101, 6114, 6111. This is an open ended project in the sense that more animations can be added to this site over time.
+Directors of three-dimensional movies sometimes use 'stereo calculators' to compute the simulated depth of objects in the film show to the viewer in order to maximize the stereoscopic effects and maintain comfortable viewing. However current calculators have limited ability to visualize the results of the calculations. This project will combine stereo calculations with visualization software to assist the director in artistic and technical decisions.
-====== Web-based digital signage ======
-**Supervisor**: John Amanatides
+====== Three-Dimensional Context from Linear Perspective for Video Surveillance Systems ======
-**Required background**: General prerequisites
+**Supervisor**:  James Elder
-**Recommended background**: CSE 3221, CSE 3214
+**Requirements**:  Good facility with applied mathematics
 __Description__
-Digital signs are increasingly used in many modern buildings to direct people to appropriate rooms for meetings, services, etc. Unfortunately, "programming" them is non-trivial, especially for non-technical people such as administrative staff. The goal of this project is to make using digital signs much easier for such people.
+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.
+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.
+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.
+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.

+====== Estimating Pedestrian and Vehicle Flows from Surveillance Video ======
+**Supervisor**:  James Elder
+**Requirements**:  Good facility with applied mathematics
+__Description__
+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.
+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.
+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.

-One way to do this is to utilize what administrative staff are really good at: dealing with calendars. By assigning calendars to individual rooms/organizations/events, and having the digital signage software interpret this calendar data to display the day's events, an easier-to-use signage system can be developed.
-More specifically, the deliverables of this project include a digital signage system for Bethune College. Some of the technologies that you will be expected to learn/use include Javascript, JQuery, HTML, CSS, and ical/CalDAV. We expect to go open source with this software so that others can use it as well. The deliverables will also include an analysis of what it takes to scale this type of signage campus wide, including provisions for campus alerts/emergency announcements.

+**Required background**: General prerequisites, at least a B+ in CSE 3311
+**Recommended background**: Knowledge of Javascript a plus
+__Description__
+The Selenium IDE is an integrated development environment for Selenium scripts. It is implemented as a Firefox extension, and allows you to record, edit, and debug tests of web applications. The Selenium IDE is a recording tool, or you may edit your scripts by hand. With autocomplete support and the ability to move commands around quickly, Selenium IDE is the nice environment for creating webtests no matter what style of tests you prefer.
+Tests can be translated to Java (JUnit), C#, Python etc. It can be extended to [[http://seleniumhq.org/about/platforms.html|any language]] that can make HTTP calls.
+The goal of this project is (1) to translate Selenium tests into tests that can be run under Eiffel (e.g. via ESpec or AutoTest), and (2) to provide a complete Eiffel web application creation template (with embedded database such as sqlite) for creating and testing web applications.

 __Description__
-A fundamental step in computer-assisted surgery is registration where the anatomy of the patient is matched to an image or model of the anatomy. For some types of orthopaedic procedures, registration is performed by digitizing the locations of points on the surface of a bone and matching the point locations to the surface of a model of the bone. Here, a surgeon uses a pointer that is tracked using an optical tracking system to measure registration point locations on a patient. A registration algorithm is used to compute the transformation that best matches the points to a model of the anatomy.
+Quantified Propositional Logics (QPL) plays an important role in a number of computer science disciplines from the theoretical computer science to knowledge representation and verification. There are also a number of open problems concerning this logic, and formulated more than 70 years ago, that can be finally solved (or at least approached) using automated reasoning techniques. The first step in such investigations has to be the design and implementation of a theorem prover, or automated reasoning system, for QPL. Such a system should, in principle, be able to determine whether or not a given formula of QPL is a theorem (or a tautology) in this logic.
+The theorem prover for QPL is to be designed, implemented, and fully tested.
-Virtual navigational information (such as where to drill or cut the bone) can be provided to the surgeon after the registration transformation has been established. Here, a surgeon is using a tracked surgical drill to drill a hole along a pre-operatively defined path. Notice that the surgeon looks at the virtual navigational information instead of the patient when performing this task.
+Background: Various variants of QPL have been formally formulated for the first time in the 1920s by a number of logicians and mathematicians. In modern computer science, QPL plays a significant role in theoretical computer science (proof complexity, satisfiability) as well as in verification and AI.
-Computer-assisted surgical navigation depends on having an accurate registration. If the estimated registration is inaccurate then the navigational information will also be inaccurate, which may lead to errors in the surgical procedure. It is of great interest to know the accuracy of the estimated registration.

+__Description__
+Have you ever considered writing your own emulator of an interesting system?
+There has been a substantial activity in building software emulators of historically significant computers, game consoles, and, recently, smart communication devices. As a result, there is at least one emulator of almost every significant system. This activity contributes, in the first place, to the preservation and dissemination of significant hardware and software technologies. It also allows for cost-effective development of contemporary software and hardware. The project's objective is to design and implement an emulator of the NABU Network -- one of the earliest "proto-Internet" networks. The emulator is to be implemented in Java.
+Background : The NABU Network was designed and implemented by a Canadian company NABU Manufacturing between 1981 and 1983. The underlying idea behind the network was to link home personal computers to cable television networks which would supply a continuous, high speed stream of computer programs and information (at the rate of 6.5 Mbits per second) to almost an unlimited number of users. Cable television was a uniquely ideal technology for NABU to deliver software and data to home computers because of its high bandwidth and networking capabilities.
+After the official launch on Ottawa Cablevision in October of 1983, the NABU Network was introduced by Ottawa's Skyline Cablevision in 1984 and a year later in Sowa, Japan, via a collaboration between NABU and ASCII Corp. NABU Network subscribers could rent or buy a NABU PC and dedicated network adaptor, and use an ordinary television set as a display monitor. Once connected to the network, a user could choose from various application programs and services in categories including entertainment, information and guides, education, and professional programs. Dedicated NABU magazines, newsletters, programming guides, and user groups provided subscribers with supplementary information and support.

The project's objective is to design and implement an emulator of the CPS/1 computer -- one of the earliest commercially available microprocessor-powered computers.
+BACKGROUND: The CPS/1 computer was designed and built by a Canadian company Microsystems International Ltd between 1972 and 73. The computer was built around the first Canadian microprocessor--the MF7114--one of world's earliest microprocessors. Although none of the CPS/1 computers have survived, technical information about the CPS/1 has been preserved. This makes the design and implementation of an emulator possible.

-====== Different "snapping" techniques in drawing systems ======
+====== Better Layout Mechanisms for User Interfaces Toolkits ======
 **Supervisor**: Wolfgang Stuerzlinger
 **Required Background**: General CSE4080 prerequisites
-**Recommended Background**: CSE3461
 __Description__
-Many graphics programs implement snapping to facilitate drawing. Snapping ensures that end-points of lines meet, that the endpoint of one line correctly "touches" another, that objects align side-to-side, etc. One problem of simple snapping techniques is that one cannot position objects arbitrarily close together - otherwise the snapping technique interferes. A novel snapping technique "Snap-and-Go" circumvents this problem by slowing the cursor over the line, instead of snapping it close to the line. The objective of this project is to implement several snapping techniques for two-dimensional drawing systems and then to perform an evaluation with a small user study.
+The layout mechanisms for many GUI toolkits are hard to understand and often difficult to use. This project investigates new, easy-to-understand layout mechanisms and evaluates an implementation of one of them in a comparative user study. Platform: any modern GUI toolkit.

 __Description__
-Previous work by the supervisor resulted in a novel and highly accurate Virtual Reality tracking system that matches or exceeds the specifications of all competing systems. However, this system works only in 5 or 6-sided immersive display environment.
+Previous work of the supervisor generated a novel and highly accurate Virtual Reality tracking system based on (eye-safe) laser diodes. The speed and accuracy of this system matches or exceeds the specification of all competing commercial systems. However, this system works only in 5 or 6-sided immersive display environment.
+Recent work has adapted the system to track successfully with as little as one large display wall and has also characterized the accuracy more comprehensively.
+The next step is to generalize the system to work in normal rooms, which may have lamps, shelves, etc. Here, visibility obstructions play a significant role and predicting these obstructions can be used to increase the tracking accuracy. This project will simulate a new method for visibility obstruction prediction to detect how big an increase in accuracy can be expected.
-This project is the first step towards an adaptation of the technology for more general environments. In particular we target normal rooms and immersive displays with less than 5 screens. The technical work involves adapting the simulation software for the previous device to simulate a new design, and iteratively optimizing that design based on the results obtained.
+====== Extensions to a 3D Modeling System ======
+**Supervisor**: Wolfgang Stuerzlinger
+**Required Background**: General CSE4080 prerequisites
+__Description__
+[[http://www.k-3d.org|K-3D]] is a successful, open-source, 3D modeling system, that can even deal with million-polygon models in real-time. This project aims to improve the user interface for K-3D by adding several novel 3D manipulation techniques. While all the mentioned operations already exist in in K-3D, the user interfaces are typically fairly inefficient and/or require significant learning. Depending on the outcome, the results of each project may even be merged back into the K-3D distribution.
+Each of the following two items can be considered a separate project:
+  * Integration of an existing implementation of a 3D sliding technique, which greatly facilitates 3D object movement.
+  * The ability to draw new "lines", rectangles, and other 2D constructs in a simple manner onto surfaces. This ability greatly simplifies many interesting operations, such as the creation of extrusions, holes, etc.
