Research on the Application of Image Enhancement Algorithms in Printing Defect Detection

摘要

This article mainly aims at the application research of image enhancement algorithm in printing image defect detection process, and the purpose is to establish a better foundation for the analysis of image defects, realizing the online monitoring of the printing quality more accurate. For the actual production situation of printing, according to the characteristics of different of printing images, chose histogram equalization, contrast linear broadening, median filtering, using MATLAB to carry on the simulation experiment of image enhancement, through the experimental analysis and comparison of the enhancement effect, further verify the advantages and disadvantages of these algorithms, to provide the basis for selection of image enhancement algorithm in the practical application of printing defect detection.
