对于BGR↔Gray 的转换, 我们 使用的 flag 就是 cv2.COLOR_BGR2GRAY。 同样对于 BGR↔HSV 的转换 我们用的 flag 就是 cv2.COLOR_BGR2HSV ''' import cv2 from pprint import pprint flags = [i for i in dir(cv2) if i.startswith('COLOR_')] pprint(flags) #在 OpenCV 的 HSV 格式中 H 色彩...

对于BGR ↔ gray 灰色的转换,我们使用cv2.COLOR_BGR2GRAY flag。相似地,对于BGR ↔ HSV,我们使用cv2.COLOR_BGR2HSV flag。要获得其他还有哪些flag,只需在Python终端中运行以下命令: import cv2 flags = [i for i in dir(cv2) if i.startswith('COLOR_')] print (flags) # 运行结果如下 ['COLOR_BA...
