The development of embedded systems (namely ES, for the short) is a technique with emphasis on practice training, therefore, it is very significant of setting up a good experimental teaching system and a scientific practice environment for the course of embedded system. Based on the consideration above, some noticeable problems of establishing experimental teaching issues are firstly studied in this...
In this paper, a descreening algorithm based on wavelet is given. Wavelet decomposition is used to eliminate the halftone noise while preserving most of the original image contents. First, convert the color image to color space CMYK with the linear transformation. Then design the corresponding filter according to the direction of each channel after wavelet decomposition. Furthermore, optional nonlinear...
