With the rapid development of science and technology, video monitoring has entered in to all walks of life, how to use computer for video image processing, analysis and understanding is an important research field of computer image mining.How to combine the computer technology with video monitoring system is the perfect combination of modern monitoring system development trend, has far-reaching significance. Modeling and weighted optimization DirichletDirichlet Modeling and Optimization.dual-HDP model for discrete data sets (such as document collection) probabilistic modeling growth model is a four-Bayesian model, a brief description of the document, to retain the essence of statistical information to help efficiently handle massive documentation set.Consider k themes document d k in i-th word w i of the probability can be expressed as follows:
