Binarize all images and detect the edges, with M athematica's built-in functions Binarize and EdgeDetect .
Calculate the integral image of each image. The process is detailed in [19]. The calculation of the integral image is not necessary, but vastly speeds up the algorithm by allowing quick calculation of the number of pixels in a given box.
We take ϵ from three pixels to four pixels, with a step size of only 1.
