英文摘要：

In order to solve the object detection and localization in the complicated image, this paper presents an algorithm for object detection and localization based on random forest. The Scale Invariant Feature Transform（SIFT） local features are used to construct a random forest classifier. A tree-structured discriminative codebook model is constructed by all leaf nodes of a decision tree. The discriminative codebook is used to estimate the object＇s location via a probab!listic computation called probabilistic Hough vote. Experimental results show that the proposed algorithm has higher efficiency, and can provide a better detection results in a complicated environment.
