Abstract

In this paper, a new preprocessing method is proposed to solve the problem that the image of the print screen coding image is not ideal because the information bit is small, the symbol is not clear and the noise is serious. This paper focuses on the algorithm of image filtering based on compression sensing and morphology and image skew correction based on Gabor wavelet. Compared with the traditional filtering, the combined filtering algorithm can reduce the noise while enhancing the protection of image feature information. The improved hough transform algorithm is also more suitable for coding image processing to achieve more accurate tilt correction. The experiment proves the superiority of the proposed algorithm.
