implementation of anisotropic diffusion for greyscale images
comparative implementation of gaussian filtering
compute connected components of an image.
e.g., run anisotropic diffusion for 80 iterations and compute the connected components to get a label map
apt-get install libpng-dev
make apply
bin/apply -i <input png file> -o <output anisodiff image> -a -n 100
bin/apply -i <input png file> -o <output isodiff image> -g -n 100
bin/apply -i <input png file> -o <output label image> -c -n 1
