I only see this description in this [link](https://docs.opencv.org/master/de/de1/group__video__motion.html#ga2beb2dee7a073809ccec60f145b6b29c), it hasn't a very detailed explanation, so I'd like to know where can I find a more detailed explanation.The official web document says "Length of the history", what "Length of the history" is?
**My code:**
import os
import time
import cv2
def main():
img_src_dirpath = r'C:/Users/Shinelon/Desktop/SRC/'
dir = r'D:/deal_pics/' + time.strftime('%Y-%m-%d') + '/'
if not os.path.exists(dir):
os.makedirs(dir)
img_dst_dirpath = dir
history = 60
varThreshold = 16
detectShadows = True
mog2 = cv2.createBackgroundSubtractorMOG2( history, varThreshold, detectShadows )
for f in os.listdir( img_src_dirpath ):
if f.endswith( '.jpg' ):
img = cv2.imread( img_src_dirpath + f )
mog2.apply( img )
bg = mog2.getBackgroundImage()
cv2.imwrite( img_dst_dirpath + f, bg )
cv2.destroyAllWindows()
if __name__ == '__main__':
main()
