Tool to sharpen (filter?) mriimages

Hi Folks
I was wondering if someone has a suggestion for a tool that sharpens MRI images?
I have in the past opened images in matlab applied a sharpening filter and saved them again, but I am looking for an option that uses command line tools.
Suggestion anybody?


We don’t have a sharpening tool in MRtrix but you could use mrfilter and the Difference of Gaussians - Wikipedia method to enhance edges without blowing up the noise. If you have recommendations for robust parameters or better sharpening methods, it might be useful to add this to population_template to sharpen the average template during construction.


If you want to have a peek at this feature branch, there’s a simple sharpening convolutional filter, as well as an unsharp mask filter. Open to suggestions for other filters that may be of utility.
