In the past decade, the bag-of-feature model has established itself as the state-of-the-art method in various visual classification tasks. Despite its simplicity and high performance, it normally works as a black box and the classification rule is not transparent to users. However, to better understand the classification process, it is favorable to look into the black box to see how an image is recognized...
Moving target classification plays a very important role in intelligent video surveillance system. A method for moving target classification in video sequences based on features combination and SVM is presented in this paper. In this method, single Gaussian background model based on the background difference method is used to achieve the motion detection, Hu moment features in moving target are extracted,...
In this paper, a robust gait recognition algorithm based on key frame and ellipse model is proposed, which solves the problems including finding key frames on discontinuous contour segmentation and accurate feature extraction on ellipse model. Firstly, a robust extraction algorithm of key fame is introduced, which makes detection of key fames easier and more accurate. Secondly, human bodies corresponding...
