cv2.error: OpenCV(4.5.5) /io/opencv/modules/imgproc/src/thresh.cpp:1659: error: (-210

problem Description¶

Call ret, thresh = cv2.threshold(seg, 127, 255, cv2.THRESH_BINARY) for binarization, appear

cv2.error: OpenCV(4.5.5) /io/opencv/modules/imgproc/src/thresh.cpp:1659: error: (-210:Unsupported format or combination of formats) in function 'threshold'

solutions¶

My seg array is of type np.int64 by default, but the above function requires uint8, so adding the following statement to seg can solve the problem

seg = seg.astype(np.uint8)
