5 x 5 Sobel template found in Feature Extraction & Image Processing for Computer Vision Third Edition by Mark S. Nixon and Alberto S. Aguado Section 4.2.1.4. Sobel edge-detection operator pp. 146-153. Formulas for deriving 7 x 7 Sobel template also found there. smoothx_win = (winsize - 1)!/((winsize - 1 - x_win)! * x_win!) Pascal(k, n) = n!/((n-k)! * k!) if ((k >= 0) && (k <= n)) 0 otherwise diffx_win = Pascal(x_win, winsize-2) - Pascal(x_win - 1, winsize-2) Sobel x template = sum from xwin = 0 to winsize-1 sum from ywin = 0 to winsize-1 of smoothy_win * diffx_win Sobel y template = sum from xwin = 0 to winsize-1 sum from ywin = 0 to winsize-1 of smoothx_win * diffy_win
