Skin detection has been considered as the principal step in many machine vision systems,such as face detection and adult image filtering.Among all these techniques,skin color is the most welcome cue because of its robustness.However,traditional color-based approaches poorly perform on the classification of skin-like pixels.In this paper,we propose a new skin detection method based on the cascaded adaptive boosting(AdaBoost) classifier,which consists of minimum-risk based Bayesian classifier and models in different color spaces such as HSV(hue-saturation-value),YCgCb(brightness-green-blue) and YCgCr(brightness-green-red).In addition,we have constructed our own database that is larger and more suitable for training and testing on filtering adult images than the Compaq data set.Experimental results show that our method behaves better than the state-ofthe-art pixel-based skin detection techniques on processing images with skin-like background. 展开更多
