Research on Error Diffusion Algorithms Based on Digital Image Feature Matching

Abstract

In this paper, an improved algorithm of error diffusion is provided, which is better than the traditional error diffusion algorithm in processing image boundary, contour and texture details. It can make the outline of printed image more clear and display better under the same print equipment or print-arts conditions. Based on the original error diffusion algorithm, this algorithm extracts and enhances the edge contour and texture feature of halftone images, optimized the error diffusion algorithm. The result has the best matching of the display effect of the printed image in the smooth part and the edge contour part.
