摘　　要：提出了一种广义直方图的构造方法并将其用于彩色图像均衡化增强。针对传统直方图均衡化方法实现彩色图像增强并不具有普适性的不足,将传统灰度图像直方图定义进行修改并得到一种广义灰度图像直方图,将其用于彩色图像在HSV空间实现均衡化增强。实验结果表明,所建议的广义直方图均衡化彩色图像增强方法是有效的,且比传统直方图均衡化方法能取得更好的增强效果。The generalized histogram is constructed and applied in color image enhancement by histogram equalization.To consider that classical histogram equalization method has not universal suitability properties in color image enhancement,classical histogram of gray image is firstly modified to obtain a generalized histogram of gray image,then color image is enhanced by the generalized histogram equalization in HSV color space.Some experimental results show that the color image enhancement method proposed in this paper is feasible,and much better effect than that of classical histogram equalization.
