Anisotropic diffusion

Anisotropic diffusion capabilities in GIL are demonstrated by the program anisotropic_diffusion, compiled from the sources example/anisotropic_diffusion.cpp.

Synopsis

anisoptropic_diffusion input.png output.png gray|rgb iterations kappa

• The first parameter must be the full path to an existing image in the JPEG format for anisoptropic_diffusion to process
• The second parameter is the full path to the output image of anisotropic_diffusion. The directory will not be created and must exist.
• The third parameter is the colour space: either gray or rgb
• The fourth parameter is the number of iterations, which must be a positive integer
• The fifth and last parameter is the value of the kappa constant

Note that both the input and the output images must be in the PNG format.

Specific requirements
