| 摘 要： | 利用一种基于RGB亮度分级的图像预处理方法,在源图像的R、G、B三个分量上对图像进行亮度分级合并,以减少自然场景图像的颜色数目,在不破坏源图像结构的前提下降低图像的复杂度,同时又保证了较好的通用性。

| Abstract: | The paper studies a preprocessing method based on classification of RGB image bright- ness, in which, brightness is classified and merged in the three components R, G, B of original image, in order to reduce the number of natural scene images in color, reduce image complexity without dama- ging the structure of the image, moreover, guarantee the better universality. |
