Witryna23 wrz 2024 · It obtains an initial estimate of the crosscorrelation peakby an FFT and then refines the shift estimation by upsampling the DFTonly in a small neighborhood of that estimate by means of amatrix-multiply DFT. With this procedure all the image points are used tocompute the upsampled crosscorrelation. Witrynadest = cv2.Laplacian(source_gray, cv2.CV_16S, ksize=3) abs_dest = cv2.convertScaleAbs(dest) Show the output: plt.imshow(abs_dst, cmap="gray") Now you can see the Laplacian filter gets the mug edges clearly and also takes in the internal text on the mug. Pretty decent right? This is how you can apply an edge …
