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. WebJan 1, 2024 · Dilation has the opposite effect on erosion. It adds a layer of pixels to both the inner and outer boundaries of regions. That is, the value of the output pixel is the maximum value of all pixels in the neighborhood.
