A fast generator of gaussian mixture samples with a general ND dimensional calling syntax.
Permit to sample from a simple multivariate process to several gaussian mixture in a easy way.
Please run mexme_sample_mvgm.m to compile on your own platform. (Be sure to mex -setup is done before)
A simple example demonstrating how to track an object with particle filter. Likelihood function is based on Bhattacharya distance of color histograms.
