ParticleFilter particle filter object tracking "ParticleFilter.java (mxj external) implements a (slightly simplified) version of the popular particle filtering tracking algorithm. Basically, particles of a given target sample the image. Those with high probability mass (i.e. over a target's pixel) are more likely to be sampled in the next frame. In this way, a target's particles tend to stick with it."
