1.创造窗口，创造轨迹条
cv2.namedWindow("TrackBars")
cv2.resizeWindow("TrackBars",640,240)
cv2.createTrackbar("Hue...createTrackbar("Val Min","TrackBars",85,255,empty)
cv2.createTrackbar("Val Max","TrackBars",255,255,empty)
2.把轨迹条的参数改变和图片关联起来...mask=mask)
4.完整代码
import cv2
import numpy as np
def empty(a):
pass
path="D:/shijue/bij.jpg"
#创建轨迹条...)
mask = cv2.inRange(imgHSV, lower, upper)
imgResult=cv2.bitwise_and(img,img,mask=mask)
cv2....namedWindow("Orginal",0)
cv2.resizeWindow("Orginal",600,400)
cv2.namedWindow("rest",0)
cv2
