摘要
图像恢复是图像处理领域的热点问题之一。利用导致图像退化的先验知识,沿着图像退化逆过程进行恢复。根据运动模糊图像的成像原理,建立了运动模糊图像的退化模型,结合图像复原的基本数学模型,运用积分变换以及微分数值化方法,建立了匀速运动模糊图像恢复的离散化过程,最后推导给出了匀速运动模糊图像恢复的离散化数学模型。该模型只利用了产生模糊的相关参数以及能够获取的退化图像信息,结果简单直接,对于后续相关算法设计提供了理论上的支撑。
Image restoration is one of the hotspots in the field of image processing and it’s the reverse process of image degradation,by utilizing the prior knowledge of the reasons leading to image degradation.In this paper,a discrete mathematical model for uniform motion-blurred image restoration is proposed.And a degradation model of motion-blurred image is built that based on the principle of imaging on motion-blurred images.The final results that derived on motion-blurred images are given by using the integral transform and differential numerical method as well as the knowledge of image processing.The final formula is simple and direct so that it can refect the whole image processing,and it can provide a theoretical support for the subsequent correlation algorithm designed.
