运动模糊图像清晰度评价函数是图像恢复中评价图像质量的一个重要判据。本文首次研究了在不同方向的图像灰度差的绝对值之和与图像运动模糊方向的关系。在此基础上 ,提出了几种运动模糊图像清晰度评价函数 ,并研究了它们的优缺点和适用范围。文中建立了评价函数的数学模型 ,给出了实验结果和分析
Motion blur image sharpness evaluation function is an important criterion to evaluate image quality in image restoration. This paper first studies the relationship between the sum of the absolute values of the gray-scale differences in different directions and the direction of the image motion blur. On this basis, several evaluation functions of motion blur image sharpness are proposed, and their advantages, disadvantages and applicability are studied. In this paper, a mathematical model of evaluation function is established, and the experimental results and analysis are given
