Python OpenCV背景扣除

正如bikz05所建议的那样，运行平均法在我的5个图像集上效果很好。谢谢你的提示 ！

import cv2import numpy as npc = cv2.VideoCapture('test.avi')_,f = c.read()avg1 = np.float32(f)avg2 = np.float32(f)# loop over images and estimate background for x in range(0,4):    _,f = c.read()    cv2.accumulateWeighted(f,avg1,1)    cv2.accumulateWeighted(f,avg2,0.01)    res1 = cv2.convertScaleAbs(avg1)    res2 = cv2.convertScaleAbs(avg2)    cv2.imshow('img',f)    cv2.imshow('avg1',res1)    cv2.imshow('avg2',res2)    k = cv2.waitKey(0) & 0xff    if k == 5:        break
