The detection effect of the infrared gait image is not good by using traditional detecting methods based on the visible light mode because of its larger noise, blurrier edge and lower contrast. Therefore, a new algorithm of infrared gait detection based on chaos ant colony optimization and space-time combination is proposed. It uses background subtraction method based on temporal domain segmentation...
The key of lip-reading recognition is to analyze rules of lip shapes, and build up the corresponding relationships between lip shapes and Chinese speeches, but the difficulty of the research lies in the "one-to-many" relationship between lip shape and speeches. For this problem, the associational lip-reading recognition based on Bayesian theory was put forward by this paper. The method applied...
