I'm trying to use cv reduce to get the projection of an image onto the x and y axis.
I used:
x_sum = cv2.reduce(img, 0, cv2.cv.CV_REDUCE_SUM, cv2.CV_32S)
I get this error:
OpenCV Error: Unsupported format or combination of formats (Unsupported combination of input and output array formats) in reduce.
I can't find any more detailed documentation on how to use reduce in Python. Does anyone know where I've gone wrong?
Alternatively, is there another method I could use? calcHist() seems to only find the colour histogram of the image.
