About "dwidenoise" command

Hi,all
I have a question.
Is there any parameter that can be set for the MPPCA algorithm in the command “dwidenoise”?
Like we can change the Gaussian smoothing parameter or the search window radius of NonLocal-Means denoising algorithm to get different denoising degrees of NonLocal-Means algorithm?

Thanks,
Silver

The only parameter you can change in that algorithm is the size of the patch, using the -extent option. This can make quite a big difference in some circumstances, but it isn’t really about controlling the amount of denoising – it’s about providing enough data to the algorithm to figure out what the noise level is, if that makes sense.
