一种改善受光照影响而恶化的图像质量的方法

光照过强或者过弱会造成可见光摄像头捕获的图像灰度值偏离视觉质量好时的灰度值,并且导致图像对比度降低,使图像视觉质量变差。针对上述图像视觉质量退化原因,提出了一种图像处理算法来改善退化了的图像视觉质量。先将图像灰度值恢复到光照合适时候的水平,然后用自适应直方图均衡算法增大图像的动态范围和对比度。仿真结果证明算法达到了改善图像视觉质量的目的。

A Method of Improving the Image Quality of Deterioration Influenced by Illumination

Excessive or deficient illumination would cause the gray-level of image captured by the visible light camera departure the gray-level of images with good vision quality and lead to the reduction of the contrast of image,to worsen image vision quality.Based on such a reason,a method of image processing to improve the vision quality of image that have degraded is put forward.Firstly the gray-level of the pixel of the image is resumed to the suitable level of illumination,and then the dynamic range and contras...
