hello
i am trying to Implement the opticalflow algorithm with block matching cv.CalcOpticalFlowBM(),
but when i run i have error
***OpenCV Error: Sizes of input arguments do not match () in cvCalcOpticalFlowBM, file /home/travis/miniconda/conda-bld/work/opencv-2.4.11/modules/legacy/src/optflowbm.cpp, line 88
Traceback (most recent call last):
File "/home/kaos/PycharmProjects/untitled/16*16.py", line 56, in
optix = calcOpticalFlow(image,image2 ,'BlockMatching')
File "/home/kaos/PycharmProjects/untitled/16*16.py", line 44, in calcOpticalFlow
0, cv.fromarray( opticalFlowArrayX ), cv.fromarray( opticalFlowArrayY ) )
cv2.error***
here is the code i try all day, but didn't find where is the problem thank's
` def calcOpticalFlow( image1, image2, method="BlockMatching" ):
storageWidth = image1.shape[0]
storageHeight = image1.shape[1]
if method == "BlockMatching":
opticalFlowArrayX = np.ndarray( ( storageHeight, storageWidth ), dtype=np.float32 )
opticalFlowArrayY = np.ndarray( ( storageHeight, storageWidth ), dtype=np.float32 )
cv.CalcOpticalFlowBM(cv.fromarray(image1),cv.fromarray(image2),
(16,16),
(5,5),
(1,1),
0, cv.fromarray( opticalFlowArrayX ), cv.fromarray( opticalFlowArrayY ) )
return ( opticalFlowArrayX, opticalFlowArrayY )
image = cv2.imread('2.jpg',cv2.CV_LOAD_IMAGE_GRAYSCALE)
image2 = cv2.imread('3.jpg',cv2.CV_LOAD_IMAGE_GRAYSCALE)
optix,optiy = calcOpticalFlow(image,image2 ,'BlockMatching')`
