Weighted Adaptive Histogram Equalization Based on Exponential Function

介绍了直方图均衡 (HE)和自适应直方图均衡 (AHE)对比度增强方法 ,进而提出了一种基于幂函数形式的加权自适应直方图均衡 (WAHE)法 ,并给出其滑动窗口权矩阵生成方式及直方图分布计算方法 ,最后给出数字

Histogram equalization (HE) and adaptive histogram equalization (AHE) methods are introduced. On the base of them, weighted adaptive histogram equalization (WAHE) method based on power function is presented, and the generating mode of weight matrix and the algorithmic method of histogram distribution for the sliding window is given. Finally, the processing result of a digital X-ray image is given, and its effect is relatively satisfactory.
