Abstract:Human detection is fundamental for human localization, recognition, and tracking. And it is still a difficult problem because of environment complexity and vision system movement. A new human detection algorithm based on mobile robot vision system is proposed to solve the problem effectively. The approach consists of the following two steps: (1)Waveletbased multiscale edge detection combined with edgelinked operator method is introduced to extract the edges of images. In this image a new morphology method is employed to get the object contourclosed for improvement of the correct recognition rate. And invariant Hu moments are calculated as pattern features vectors. (2)The adaptive Gaussian kernel soft margin support vector machine (CSVM) classifier is designed to distinguish human images from nonhuman ones. Experimental comparisons have been conducted,including adaptive Gaussian CSVM classifiers based on different features and the classifiers with different classification methods. The results validate effectiveness and robustness of the algorithm.
