Wipe transition is an important type of gradual transition, but false and missed detection are very serious in most literatures due to noise and motion. In the proposed scheme, color sub-image and edge sub-image of each frame are decomposed by Db-4 wavelet transition. In detecting potential wipe transition, the color sub-image is divided into 8*8 pixel(More)
A new method of affine object recognition and affine parameters estimation is presented. For a real-time image and a group of templates, firstly, we segment the object regions in them and compute their covariant matrices. Secondly, normalize the ellipse regions defined by covariant matrices to circle regions to get rotational invariants, and compute the(More)
One method was proposed in this paper which can update observed data sparsely and reconstruct the scene model densely so that the monocular vision system can observe and reconstruct the target dynamically. On one hand, by combining the classic solutions for observation systems and introducing the coherence-detection and the maintenance-judgment into it,(More)
