基于XYZ颜色空间的图像颜色复原

摘要

颜色是图像的重要特征,目前对图像颜色复原时存在较大失真现象.依据图像颜色信息损失的物理原因,提出在XYZ颜色空间对原图像进行辐射衰减补偿和去除大气光幕影响,从而实现图像的颜色信息复原.采用复原前后图像颜色与景物颜色的色差衡量图像颜色的复原效果,实验结果表明与现有的图像颜色复原算法相比,本文提出的算法复原的图像颜色失真程度最小,有利于进一步的图像特征提取.%Color is an important characteristic of the image, at present, there is a large distortion in the image color recover-y. According to the physical reason of the loss of image color information, we propose that by compensating for radiation at-tenuation and removing the effects of atmospheric light curtains in the XYZ color space to achieve the restoration of the loss of image color information. The color difference between the image color and the natural scene color indicates the effect of color recovery,the experimental results show that the algorithm proposed is more realistic for the image color and is helpful for fur-ther image feature extraction.
