快门编码模型重影模糊图像盲复原方法

摘要

A coded-shutter model is propose d to approximate the nature of overlap-blur, which often arises in the criminal detection forensics work. A blind image deeonvolution algorithn is designed based on the coded-shutter model. The experiment results show that when tested on the real overlap-blurred photographs, the proposed algorithm can restore the information of interest in the blurred images effectively%针对刑侦取证工作中经常出现的一种重影模糊图像,提出了一种快门编码模型来近似模拟重影模糊的本质,利用快门编码模型对重影模糊图像进行盲复原处理.实验结果表明了该快门编码模型对复原重影模糊图像的合理性,对实际拍摄的重影模糊图像,该算法能够有效地复原出模糊图像中的感兴趣信息,具有较高的实用性.
