Research on distance education image correction based on digital image processing technology

摘要

Abstract Distance education is generally developed through live broadcast or video playback. Because of the influence of various factors in the process of distance education, the pixel characteristics in the original educational resource image will change. Based on this, this study is based on digital image processing technology to correct the distance education image. In addition, this study uses the layered processing model to decompose each color channel and then process the image brightness channel, which effectively reduces the computational overhead while ensuring the fusion effect. Finally, combined with comparative experimental research, the performance analysis of the algorithm is carried out. Research shows that the algorithm of this study has good performance in image correction and can provide theoretical reference for subsequent related research.
