In this paper we address the problem of design a wavelet lossy image coder that allows edge and texture preserving using a modified version of SPIHT coder. First, we obtain the edge map of an input image by means of the SUSAN edge detector. Second, a reversible wavelet transform is made. Third, the coordinates of edges or textures are mapped to the correspondent position in the wavelet domain. Finally,...
It's significant to convert a planar image into a stereo one. In this paper we used a method which needs to segment an image into sub-blocks to realize this kind of conversion; parameters such as random variables were used to control the procedure. We presented two quantitative criterions, cross-entropy and root-mean-square error, to evaluate the stereo effect. Furthermore, the stereo effect that...
