In this paper, a novel plane fitting algorithm with low complexity and high accuracy is proposed to refine the depth maps generated by stereo matching. We first compute the confidence coefficient for each pixel in the depth map by cross checking and stable pixel calculation. According to the outlier pixel percentage for each segment, we choose one method, either proposed weighted least square error...
In this paper, a novel image watermarking scheme based on independent component analysis (ICA) is proposed. In the proposed scheme, the original image is sub-sampled firstly to obtain four sub-images, and the features of the original image are extracted by performing ICA to these sub-images, and then the feature, which has the largest variance, is selected out to be watermarked on its block DCT coefficients...
