The perception color space HSI in this algorithm is adopted.Three color components of a color image and more potential edge patterns are integrated for solving the feature extraction problem.A fast and automatic threshold technique based on human visual perception model is also developed.The vertical edge projection and horizontal edge projection are adopted for locating left-right boundary of vehicle and top-bottom boundary of vehicle, respectively. Very promising experimental results are obtained using real-time vehicle image sequences, which have confirmed that this proposed location vehicle method is efficient and reliable, and its calculation speed meets the needs of the VRS.展开更多

After 30 treatments, there is a significant difference between the therapeuticeffects of two groups (P < 0. 05 ), the former is better than the latter. It suggests that the method ofneedling around the projective area on the scalp of the focus is an effective and a feasible展开更多

Based on integral projection of local binary image pixels and pixel clustering techniques, a set of a priori knowledge based algorithms have succeeded in locating eyes, nose and mouth, and uprighting the tilt face. The proposed approach is superior to other methods as it takes account of photos with glasses and sha dows, therefore suitable for processing real ID type photos.展开更多
