Research and application on clarity-evaluation-model for the cross-line gray-scale image

摘要

The image clarity evaluation function has some characters, such as category excessive, complicated calculation and non-uniform standard. In this paper, a theory model on clarity evaluation of the cross-line gray-scale image is proposed, by analyzing its adaptability, and an improved clarity evaluation model is deduced. The experiment results show that the improved model accords with the reality of the cross-line gray-scale image and it is effective.
