Remarks

The SRADAnisotropicDiffusionCommand (Speckle Reducing Anisotropic Diffusion) reduces noise and speckling in images while preserving the edges.
The number of iterations controls the number of times the filter will be applied to the image. The lower the number of iterations, the faster the filter will perform. Higher iterations typically mean clearer results.
This command processes only the entire image. It does not support regions.
This command supports 8, 16-bit grayscale images and 24, 32-bit colored images.
This command supports signed/unsigned images.
