OpenCV normalizes with the Log10 function for all three of its matching computations. I tried normalizing each pair of Hu moments with the ratio to each pair's maximum value max (Ai,Bi) and I tried normalizing each pair to a vector length of 1 (divide by sqrt of the sum of the squares). Ver mais I like the idea of normalization (crop and resize). But after shrinking an image, its originally closed contour might be broken into multiple disconnected parts, due to the low resolution of pixels. The result of cv2.matchShapes()is … Ver mais By filling the shape, we take area into consideration. The result looks better, but DVI still beats HDMI for having a more similar height or Height/Width ratio. We want to ignore that. Ver mais By resizing all to the same size, we eliminate some ratio in the dimensions. (300, 300) works well here.
