【摘要】 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。更多还原

【Abstract】 Clarity-evaluation-function of motion blurred image is an important criterion for evaluating the quality of image restoration. The relationships in various directions between the function,the sum of absolute-value of gray difference of image, and the-motion blur direction are studied for the first time in this paper. Based on that, some evaluation-functions of motion blurred image are proposed,and their advantages and disadvantages are also discussed. The mathematical models of these functions are established, and the experimental results and analysis are also given.更多还原
