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 … 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.
