# 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 ouput images must be in the PNG format.
