摘　　要：本文提出了一种基于直方图匹配的颜色校正方法,其基本思想是在目标图像和源图像的直方图间建立像素的映射关系,与一维直方图匹配不同,通过对三维空间的连续采样,建立起类似一维的匹配函数,而又完全满足三维直方图的特性,并最终实现对颜色图像的校正,实验结果表明了算法的有效性。This paper prpopses a color correction method based on histogram matching. The primary idea of the work is that mapping relation is established between source image and target image histograms. Different with 1D histogram matching,by sequential samping in 3D space,matching function can be estab-lished similar to 1D case while fully sat-isfied 3D histogram characteristic,to achieve color image correction. Exprimental re-sults show the validityof our method.
