A new method is proposed in this paper for feature extraction based on geometric flow of images and the second generation of Bandelet transformation,where Bandelet coefficients and their statistical values were extracted as the feature of human images.Afterwards the full body and body parts classifier were trained on AdaBoost algorithm.At last,likelihoods of each body parts were computed combined with Bayesian decision-based approach to perform human detection.The results of human detection experiments indi...
