Preliminary Algorithm

1. A simple color segmentation to break the scene into the a priori known colors through hard coded thresholds.
   1. Preset limits.
   2. User can select colors.
   3. Segmentation will adapt to changing scene through neural net.
2. Connectedness analysis and centroid finding to determine distinct targets - the ball, and centers of robots.
3. Pattern matching to identify friendly robots.
4. Convert centroids from image space to real space.

• GTrack BORG Lab color tracking software. Tucker Balch reccomended this. Which uses CMVision
• CMvision I read the source code, pretty primitive algorithms and some bickering among the developers in the very few comments... wow.
• Resources_for_Learning
• Algorithm development will be done in MatLab

GPU Image Processing

So, a few weeks ago, we were kicking around the idea of using the GPU for image processing, I saw some papers, links etc and thought I'd share

• Wikipedia GPGPU
• NVIDIA paper
• NVIDIA SDK and code samples (some image processing stuff)
• NVIDIA SDK II more code etc.
• GPGPU always seems to be down...
• OpenVidia ACM/SIGGRAPH winner wow
• GPGPU tutorials
