HSV色彩空间特定颜色提取 inRange函数使用实例

代码如下：

import cv2 as cv
import numpy as np

def extrace_object_demo():
    capture = cv.VideoCapture(0)
    while(True):
        ret, frame = capture.read()
        if ret == False:
            break;
        hsv = cv.cvtColor(frame, cv.COLOR_BGR2HSV)
        lower_hsv = np.array([35, 43, 46])
        upper_hsv = np.array([77, 255, 255])
        mask = cv.inRange(hsv, lowerb=lower_hsv, upperb=upper_hsv)
        dst = cv.bitwise_and(frame, frame, mask=mask)
        cv.imshow("video", frame)
        cv.imshow("mask", dst)
        c = cv.waitKey(40)
        if c == 27:
            break

def extrace_object_demo2():
	src = cv.imread("E:/opencv/sources/samples/data/opencv-logo.png")
	hsv = cv.cvtColor(src, cv.
