中文说明：这种技术通常升级全球对比
English Description：
This technique usually escalates the global contrast of several images, especially once the utilizable data of the image is represented by nearby contrast values. All the way through this adjustment, the intensities could be better distributed on the histogram. This happens for parts of lower local contrast to improve a larger contrast. Histogram equalization accomplishes this by successfully spreading out the absolutely frequent intensity values. The strategy is advantageous in images with backgrounds and foregrounds which are generally bright or both dark. Specifically, the strategy can lead to raised
