WebJan 8, 2013 · It is normally performed on binary images. It needs two inputs, one is our original image, second one is called structuring element or kernel which decides the nature of operation. Two basic morphological operators are Erosion and Dilation. Then its variant forms like Opening, Closing, Gradient etc also comes into play. WebGenerates a Euclidian distance map (EDM) from a binary image [38]. Each foreground pixel in the binary image is replaced with a gray value equal to that pixel’s distance from the nearest background pixel (for background pixels the EDM is 0). The Ultimate Points ↓, Watershed↓ and Voronoi↓ operations are based on the EDM algorithm.
