python opencv获取图片信息的方法（II）

import CV2

img = CV2.imread("sk.jpg")

# BGR转化为HSV

HSV = CV2.cvtColor(img, CV2.COLOR_BGR2HSV)

# 鼠标点击响应事件

def getposHsv(event, x, y, flags, param):

    if event==CV2.EVENT_LBUTTONDOWN:

        print("HSV is", HSV[y, x])

def getposBgr(event, x, y, flags, param):

    if event==CV2.EVENT_LBUTTONDOWN:

        print("Bgr is", img[y, x])

CV2.imshow('image', img)

CV2.setMouseCallback("image", getposBgr)

CV2.waitKey(0)

CV2.destroyAllWindows()
