I am always keen to share the codes related to my papers, as i think it is the best way to promote the academics. Recently, two phd candidates from Tsinghua and Zhejiang uni. asked me for SMC-PHD filter codes, i sent to them and put it on my webpage as well This is possibly the first version of the hot SMC-PHD (also referred to as PF-PHD) filter that is open access online Have a look @ https://sites.google.com/site/tianchengli85/matlab-codes/phd-filter SMC-PHD stands for the sequential Monte Carlo (SMC) implementation of the probability density hypotheses (PHD) filter, it also says the particle filter (PF) implementation of the PHD filter
