In this chapter, we describe a GPU-based technique for finding the location of a uniquely colored object in a scene and then utilizing that position information for video effects. The technique uses a pixel shader in an atypical manner: to calculate a centroid and area rather than a per-pixel effect.
Object detection and tracking have applications in robotics, surveillance, and other fields. As the number of consumers who own computers equipped with video cameras increases, so do the possibilities of using the GPU for tracking objects for games and to enable new user-interaction models. In this chapter, ...
