Detailed description:
When trying to run pyramids as the input for the cv2.calcOpticalFlowPyrLK function the program gives out an error. when I run the cv2.buildOpticalFlowPyramid method it returns a pyramid, without any errors but as soon as I use it as input it doesn't run.
Steps to reproduce:
lk_params = dict(winSize=(21, 21), # Parameters used for cv2.calcOpticalFlowPyrLK (KLT tracker)
maxLevel=3,
criteria=(cv2.TERM_CRITERIA_EPS | cv2.TERM_CRITERIA_COUNT, 30, 0.01))
def KLT_featureTracking(image_ref, image_cur, px_ref):
image_ref = cv2.buildOpticalFlowPyramid(image_ref, (512, 512), 2)
image_cur = cv2.buildOpticalFlowPyramid(image_cur, (512, 512), 2)
kp2, st, err = cv2.calcOpticalFlowPyrLK(image_ref, image_cur, px_ref, None, **lk_params)
kp1, st, err = cv2.calcOpticalFlowPyrLK(image_cur, image_ref, kp2, None, **lk_params)
Error:
kp2, st, err = cv2.calcOpticalFlowPyrLK(image_ref, image_cur, px_ref, None, **lk_params)
TypeError: prevImg is not a numerical tuple
