ABSTRACT
Taking into account human visual characteristics, when isolated distortion pixels disperse sufficiently in an image, these pixels have minimal effect on the visual images. This study presents a color and brightness correction method based on lαβ color space transformation and excluding isolated pixels with brightness distortion. The experimental results show that the method can obtain better brightness and color uniformity in the vision, as well as make the histograms of corrected images in three channels get closer to normal distribution. Furthermore, the method suggested in this study can better reflect the transformation of surface features in the images.
