改进的图像增强直方图统计方法

为了在不增加图像增强算法复杂度, 便于硬件实现的同时得到更加清晰自然的图像, 提出了一种新的直方图统计方法。给出了改进的直方图统计和分布调整算法, 将亮度控制与直方图分区域均衡相结合, 对直方图整体分布进行修正, 以改进亮度饱和问题; 采用固定的直方图分割点分区域均衡直方图, 通过均衡后的直方图映射出增强后的图像。实验结果表明, 该方法在计算量增加较少的情况下图像具有较好的增强效果, 既避免了图像亮度出现过饱和的现象, 又突出了图像细节, 视觉效果明显优于传统方法。

In order to reduce the complexity of the algorithm of image enhancement, to simplify hardwareimplementation and to get more clear and natural image, we propose a new histogram statistics method, Presentsan improved histogram statistics and distribution adjustment algorithm. On the whole distribution histogrammodification the brightness saturation problem is improved. Uses the fixed point of histogram segmentation pointsarea balanced histogram. With histogram after balanced reflects the enhanced image. Experimental results showthat the method in the case of adding less amount of calculation to ensure the image has a better effect, not onlyensure the oversaturation did not appear, and guarantee the image detail is outstanding, has a good visual effect.The enhancement effect of this method is superior to the traditional method.
