说明：  1、读取一张图片，将其转换为HSV空间\对RGB三个通道分别画出其三维图（提示：polt_sufface函数） 2、读取彩色图像home_color；画出灰度化图像home_gray的灰度直方图，并拼接原灰度图与结果图； 3、画出彩色home_color图像的直方图，并拼接原彩色图与结果图，且与上一问结果放在同一个窗口中显示； 4、画出ROI（感兴趣区域 ）的直方图，ROI区域为 x：50-100，y：100-200，将原图home_color，ROI的mask图，ROI提取后的图及其直方图放在一个窗口内显示。 5、编程实现直方图均衡化，给出测试效果
(1. Read an image and convert it into HSV space. Draw three-dimensional images of RGB channels (hint: pol T)_ Sufface function) 2. Read color image home_ Draw a grayscale image home_ Gray histogram, and mosaic the original gray image and the result image; 3. Draw color home_ Color image histogram, and mosaic the original color image and the result image, and put them in the same window with the previous result; 4. Draw the histogram of ROI (region of interest), the ROI region is X: 50-100, Y: 100-200, the original image home_ Color, the mask image of ROI, the extracted image of ROI and its histogram are displayed in a window. 5. The histogram equalization is realized by programming, and the test results are given)
