(a) 编写一个计算图像直方图的程序。

(b) 实现在 3.3.1节中讨论的直方图均衡化技术。

(c) 对图3.8(a)进行直方图均衡化增强。

本实验报告中至少应包括：原始图像，原始图像的直方图，直方图均衡化变换函数图，增强后的图，增强后

图像的直方图。用上述实验数据解释结果图像被增强的原因。

-(A) preparing a program to calculate the histogram. (B) histogram equalization technique discussed in Section 3.3.1. Figure 3.8 (a), (c) enhanced histogram equalization. In this study, the report should include at least: the original image, the histogram of the original image, histogram equalization transformation function map, the enhanced diagram, and enhance the image histogram. The experimental data to explain the reasons for the enhancement of the resulting image.
