What does the cv::normalize(_src, dst, 0, 255, NORM_MINMAX, CV_8UC1); do in OpenCV? I went through the documentation and was unable to understand what alpha, beta, NORM_MINMAX and CV_8UC1 actually do. I am aware alpha sets the lower and beta the higher bound. CV_8UC1 stands for an 8 bit unsigned single channel. But what exactly these arguments ... python Difference between cv2.findNonZero and Numpy ... mask = np.zeros(imgray.shape,np.uint8) cv2.drawContours(mask, [cnt],0,255, 1) pixelpoints = np.transpose(np.nonzero(mask)) pixelpointsCV2 = cv2.findNonZero(mask) Which states. Numpy gives coordinates in (row, column) format, while OpenCV gives coordinates in (x,y) format. So basically the answers will be interchanged. OpenCV: Operations on arrays performs an inverse transformation of a 1D or 2D complex array; the result is normally a complex array of the same size, however, if the input array has conjugate complex symmetry (for example, it is a result of forward transformation with DFT_COMPLEX_OUTPUT flag), the output is a real array; while the function itself does not check whether the input is symmetrical or not, you can pass the ... Revision history OpenCV Q&A Forum Step 3: cv::threshold( img,...,128, BINARY_INVERSE) Step 4: cv::findNonZero() 3. Filter by Periodicity: the grid is periodic, the graph line not. The grid could be sorted out via the peaks in the Fourier Transform. Problem: not easy to handle if you don't have experience with that, and the grid is not even really periodic in your example. OpenCV: Feature Detection 16 bit x derivative of input image (CV_16SC1 or CV_16SC3). dy: 16 bit y derivative of input image (same type as dx). edges: output edge map; single channels 8 bit image, which has the same size as image . threshold1: first threshold for the hysteresis procedure. threshold2: second threshold for the hysteresis procedure.

The problem is with your Core.findNonZero call. You are providing an incompatible input Mat to it. The input is expected to be a single channel 8 bit image. From your code, it looks like you are providing a colour image to your deskew function and ultimately the Core.findNonZero call.
