我使用set xtics("20200106" "20200106","20200115" "20200115","20200124" "20200124","20200202" "20200202","20200211" "20200211","20200220" "20200220", "20200228" "20200228)
将图像转换为hsv。但是，当我使用imghsv = cv2.cvtColor(img, COLOR_BGR2HSV)将此图像转换回原始色彩空间时，图像的质量并不相同，并且出现了可见的色带。为什么会这样？
这是原始图片：Original Image
这是恢复的图像：Recovered Image
