In recent years, the research on detecting human faces in color image and in video sequence has been attracted with more and more people, but automatic human face detection from images in surveillance and biométrie applications is still a challenging task due to the computation inaccuracies and the continuous nature of some transformations. In this paper we propose a novel face detection algorithms...
This paper proposes an automatic method to recognize the hand in complex background. With this method, contour of hand in pictures can be figured out and the fingertips can be marked out. Skin color detection is used to find out the hand region out of a complex background, then a serial of morphological operations is performed to get the contour of the hand, and the computation of Fingertip-Angle...
Face detection in computer vision and pattern recognition technology as an important Subject has high academic value and commercial value. Studies the face detection based on Adaboost algorithm, and presents a face detection method based on skin color and Adaboost algorithm. First transforms the input color images form RGB space to YCrCb space, then uses morphologic methods to make area skin segmentation,...
