Traceback (most recent call last): File "example.py", line 58, in <module> flow = cv2.calcOpticalFlowFarneback(gray1, gray2,0.5, 3, 15, 2, 5, 1.2, 0) # calculating the flow between gray1 and gray2 using gunner farneback algorithm TypeError: integer argument expected, got float
if you do a :
>>> help(cv2.calcOpticalFlowFarneback)
Help on built-in function calcOpticalFlowFarneback:
calcOpticalFlowFarneback(...)
calcOpticalFlowFarneback(prev, next, flow, pyr_scale, levels, winsize, iterations, poly_n, poly_sigma, flags) -> flow
in the python repl, you can see the signature.
so, the problem, seems the flow param, you have to use None, like in the tutorial,
flow = cv2.calcOpticalFlowFarneback(gray1, gray2, None, 0.5, 3, 15, 2, 5, 1.2, 0)
Thank you very much for the kind reply. I got the following error after executing the instruction:
File "example.py", line 61, in <module> flow=cv2.calcOpticalFlowFarneback(gray1, gray2, pyr_scale=0.5, levels=3, winsize=15, iterations=2, poly_n=5, poly_sigma=1.2, flags=0) TypeError: Required argument 'flow' (pos 3) not found
