Face detection is an important first step towards solving plethora of other computer vision problems. A fast robust face detection algorithm under a skin color model with geometry constraints is proposed in this paper. An ellipse color model in the YCbCr color space is first used to detect the skin regions. A light compensation algorithm is utilized to the original image, followed by a box model to...
Biometric data are main objects of attacking behaviors to biometric system. For improving iris feature template data security to an iris recognition system, a data hiding method based on bit stream is proposed, in which an iris feature template is embedded into a face image as an example. The proposed method is applicable to present dominant iris recognition techniques. Besides the low computation...
