3D human face recognition with 3D imaging technology is a frontier in image processing and pattern recognition. The 3D real-time human face imaging system based on CIS is able to obtain corresponding 2D gray data and 3D depth data from human face. Dimensionality reduction of high-dimensional observation data is the key problem of face recognition. This paper applies LOGMAP theory to dimensionality...
Aiming at the need of personal privacy protection in the image acquisition system, paper proposes a video security algorithm used in facial protection. It fixes on the facial area in the image by face detection algorithm, regards facial area image as characteristic watermark information (large capacity watermark) and embeds them into the original image using large capacity color image watermarking...
