摘要
运动模糊图像恢复是图像处理中的重要部分。本文将计算机图形学尺度旋转引入运动模糊图像恢复中 ,提出基于尺度旋转变换的运动模糊图像自动搜索恢复模型 ,并阐述建立模型的完整过程和均方误差准则下自动搜索优化算法。实验表明 ,模型较好解决了传统运动模糊图像恢复中无参数恢复图像的缺陷 ,恢复效果良好 ,是一种有效的图像恢复方法。
Digital image restoration is one part of digital image process,while di mension rotation is one kind of transformations which discribes the graphic dire ction,dimension and form in the field of computer graph research In this paper ,s tarting with the traditional algorithm of digital image restoration,adding the d imension rotation of computer graphy,we present a new automatic restoration mod a l for restoration of motion images In the course of model making,which is base d o n the dimension rotation of computer graph we give more detailed on how to combi ne the dimension rotation of computer graph with the restoration algorithm of di gital image restoration At the same time,the related automatic restoration alg or ithm is provided Analysis predicts that as the motion parameter increased,the motion image restoration effect is unaffected either with or without the motion parameters Simulation experiments show that compared with the general restorat ion method,our model has better effect with provided parameter On the other ha nd ,t he automatic restoration effect is unaffected remarkably on the condition that n o parameters are provided,which can propose to be one good choice of motion ima ge restoration
