Research On Object Categorization Algorithms In Vedio Surveillance And Integrated Camera

With the rapid development of digital image technology, the number of pictures increase rapidly. So, how to retrieval a special picture efficient has become a major issue.In this paper, some key technology of image classification for semantic extraction has been discussed, which mainly include feature extraction in image classification. We give an overview of current approaches for feature extraction,analyze their features and how to use the feature properly. And we use the result of image classification in intelligent video surveillance to improve the performance of object tracking.At last, we give a solution of integrated camera base on blackfin 531 processor, and give the algorithm of autofocus used in the integrated camera system.
