保持图像细节的直方图均衡算法

Algorithm of histogram equalization with detail preservation

对常规的直方图均衡算法进行了改进,避免了不同灰度的像素均衡后被合并、图像细节丢失等现象。实验结果表明,改进的直方图均衡新算法既能充分增强图像的对比度,又能保持图像的局部细节,使图像具有更加自然的视觉效果。

In this paper, improvement was made in histogram equalization, which made it possible to avoid some phenomena, such as merging in the different pixels after histogram equalization, losing the local details of images and soon. The simulation results show that, with the improved algorithm, the contrast on the image can be enhanced effectively, the local details can also be preserved, and the enhanced image in a more natural manner and hence in the meantime.
