opencv-光流法

import numpy as np
import cv2
import sys

cap = cv2.VideoCapture("video2.mp4")
feature_params = dict( maxCorners = 100,qualityLevel = 0.3,minDistance = 7,blockSize = 7 )
lk_params = dict(winSize = (15,15),maxLevel = 2,criteria = (cv2.TERM_CRITERIA_EPS | cv2.TERM_CRITERIA_COUNT, 10, 0.03))
color = np.random.randint(0,255,(100,3))
ret, old_frame = cap.read()
old_gray = cv2.cvtColor(old_frame, cv2.COLOR_BGR2GRA

opencv-光流法最先出现在Python成神之路。
