随着数码相机在刑事照相中的日益普及,对于所得图像处理也就越来越多,以前有许多关于介绍去除指印干扰背景方面的文章,它们的方式主要是擦除法和滤镜法;或者在一些图像处理软件中(例如PHOTOSHOP),通过调整图像的反差达到强调痕迹;还有在RGB或HIS模式中,通过通道减运算去除干扰背景,也有一定的效果。本文介绍一种新的方法,它是通过置换去除指印的干扰背景。
As digital cameras have become more widespread in criminal photography, there has been an increase in the number of images processed, and there have been many previous articles on the background of fingerprinting interference removal, mainly by erasing and filtering; or In some image processing software (such as PHOTOSHOP), the contrast marks of the images are emphasized to emphasize the marks. In RGB or HIS mode, channel subtraction is also used to remove the interference background, and there is also a certain effect. This article describes a new method that removes background interference from fingerprinting by permutation.
