import cv2


def mouse_click(event, x, y, flags, para):
    if event == cv2.EVENT_LBUTTONDOWN:  # 左边鼠标点击
        print('PIX:', x, y)
        print("BGR:", img[y, x])
        print("GRAY:", gray[y, x])
        print("HSV:", hsv[y, x])
        print("LAB:", lab[y, x])
        print("-----------------------------------------------------")


filename = input("Please Input Your Image Or Video : \n")
image0 = cv2.imread(filename,1)
img = image0
#img = cv2.cvtColor(image0,cv2.COLOR_RGB2BGR)
gray = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
hsv = cv2.cvtColor(img, cv2.COLOR_RGB2HSV)
lab = cv2.cvtColor(img,cv2.COLOR_RGB2LAB)
cv2.namedWindow("img")
cv2.setMouseCallback("img", mouse_click)
while True:
    cv2.imshow('img', img)
    if cv2.waitKey() == ord('q'):
        break
cv2.destroyAllWindows()
