Steps done for the computation of the number of pixels assigned to each scale generated during the process of applying a Frangi Filter to the en-face image (histogram bins). Image 1 corresponds to the en-face slab image, image 2 corresponds to the enhanced vessel slab using the Frangi Filter, and image 3 corresponds to the matrix, resulting from the process of filtering the en-face slab with the Frangi Filter with four scales, with the scales on which the maximum intensity of every pixel is found.
