The goal of this project was to develop an implementation of the [[Instant Radiosity|http://graphics.uni-ulm.de/Instant.pdf]] algorithm presented by [[Alexander Keller|http://graphics.uni-ulm.de/]] in SIGGRAPH 2007. We intend to add this to our implementation of the [["virtual pit"|AR Presence Experiment]] and evaluate the usefulness of this technique in the context of augmented reality.

As part of the project, we compared the results of quasi-Monte Carlo sampling using the Halton sequence (used in the original paper) against Poisson disk sampling.

The goal of this project is to design a benchmarking tool and a questionnaire to evaluate how the different elements of an augmented reality (AR) experience relate to the concept of presence (the elimination of the sense of mediation, or subconsciously forgetting we are wearing equipment and that the AR experience is not real). For this purpose, I am working on extending an implementation of UNC's [["virtual pit"|http://wwwx.cs.unc.edu/~eve/walk_exp/]] system. More details in the [[project page|http://www.gvu.gatech.edu/ael/projects/ARexperienceEval.html]].

The purpose of this project was to gain experience implementing a few algorithms for anisotropic diffusion of images in MATLAB in order to learn uses for PDEs. We also compared the different implementations and wrote a [[report|classes/math411/411termproject.pdf]] with our results.

Introduction
News

This effort attempts to extend work by [[Supan et al.|http://staff.fh-hagenberg.at/haller/]] on the use of cameras and light probes to capture environment maps dynamically and use them for specular reflections and diffuse illumination in augmented reality. We implement one of the techniques described in:
*[[Supan, P., Stuppacher, I., Haller, M. 2006. Image Based Shadowing in Real-Time Augmented Reality, in International Journal of Virtual Reality, 2006, 5(3), pp. 1-7, IPI Press.|http://staff.fh-hagenberg.at/haller/publications/2006/Supan%20et%20al%20-%20IJVR%202006%20-%20Image%20Based%20Shadowing%20in%20Real-Time%20Augmented%20Reality.pdf]]
And we make two additions:
*Instead of using cameras or light probes in the environment, we used two cameras on a handheld mount.
**The cameras are aligned along the same axis but they point in opposite directions.
**One of the cameras is used to look at the marker, track the position of the handheld mount and be used as the real world background in the rendering.
**The other one is used to capture the environment and use it to paint an environment map in real time.
**We did this because we wanted to know how feasible the use of a back-facing webcam on a handheld device such as a cellphone or MID would be for this kind of environment capture.
**Future work should focus on the following:
***Address how to decide when to repaint certain sections of the map.
***Use CV techniques to detect and clip the silhouette of the user out of the map.
***Use parallax techniques to determine light position and shape in the real world for better illumination.
*Instead of using cube maps, we use paraboloid texture mapping
**Cube maps are prone to distortions on the seams, which are very visible on a table-top marker-based AR experience.
**Additionally, paraboloid texture maps have some advantages in terms of speed, memory usage and update (only 1-2 textures as opposed to 5-6 in cube maps) and simplicity (when requesting a particular texel, it is not necessary to compute which side of the cube map it should be extracted from).
Here is a [[presentation|papers/DynamicParaboloidEnvironmentMapsForImageBasedShadowing.pdf]] we gave.

[[Skills and Knowledge]]

Basic first-person shooter game featuring the Irrlicht 3D engine. We took one of the sample applications bundled with the SDK, and we added visual effects (particle systems, dynamic shadows, etc.), simple physics (collision detection), animated characters with a simple AI path-finding algorithm and other game logic.

Team members: Jordan Pomeroy, Brad Keck, Tena Columbel. Instructor: Professor [[Parris Egbert|http://cs.byu.edu/faculty/egbert_parris]].

We introduce a method to remove lens distortion from video streams in augmented reality (AR) applications. Our procedure precomputes shifts for the pixels in the image, and then uses a GPU shading program to apply them in real time. Our approach is more accurate than current real-time techniques, is very easily integrated into existing AR applications (and combined with other post-process video effects), and should be well-suited for GPU-enabled low-power devices, such as PDAs or mobile phones. Additionally, our approach allows for modifying the field-of-view of the resulting, dewarped image to an arbitrary field-of-view: either to a fixed field-of-view (i.e. for a head-mounted display) by integrating with the static precomputation step, or to a variable field-of-view (i.e. simulate dynamic digital zooming) in the shader program.

Update: Now I will be trying to expand this idea to stereoscopic displays and also to fish-eye lenses.

The purpose of this project was to design a prototype for a gesture-based interface for a smart conference room, build it and perform a user evaluation. We used the [[Nintendo Wiimote|http://en.wikipedia.org/wiki/Wiimote]] as our interface prototype, and we implemented the rest of the infrastructure using a [[Wizard-of-Oz|http://en.wikipedia.org/wiki/Wizard_of_Oz_experiment]] model.

==Under construction==

This project aimed to create a highly customizable and skinnable GUI application that helps pick participants during a class or a meeting. It's intended to make the process of randomly selecting a participant for some task (e.g. answering a question) fun, and ensure participants feel motivated and do not lose interest. The project was finished and it is commercially available at http://www.9999tech.com/randomselector/

The goal of this project was to build an editor that allowed for defining vector fields for particle flow that also allowed morphing between vector fields. For more information, visit the assignment's [[webpage|classes/cs7496/P5/index.html]].

Team member: David Spain. Instructor: Professor [[Jarek Rossignac|http://www.gvu.gatech.edu/~jarek/]].

The purpose of this project was to implement an alternative version of the [[relief texture mapping algorithm|http://portal.acm.org/citation.cfm?id=344947]] devised by Oliveira, Bishop and MacAllister.
