With the extensive application of digital television, video compression technology has become one of the topics which the telecommunication industry concerns most. A video compression method based on redundant discrete wavelet transforms, Delaunay triangle and triangular affine transformation is presented. The feature points and potential motion areas (PMA) are extracted in the wavelet transform domain,...
Moving vehicle recognition and tracking is the key technology in the intelligent traffic monitoring system. For the shortcomings and deficiencies of the frame-subtraction method, a binary discrete wavelet transforms based moving object recognition algorithm is put forward, which directly detects moving vehicles in the binary discrete wavelet transforms domain. For the shortages of RGB or HSV color...
A method for moving multi-target recognition and tracking in stable scene is presented. Optical flow is used to extract the velocity of pixels, and targets are recognized by combining motion character points obtained by binary discrete wavelet transforms (BDWT). A discrete kalman filter is used to track targets in the follow-up frames; the center and scale of tracking window are updated by a Mexico...
