MATLAB code for non subsampled shearlet transform

Helo

I am doing medical image fusion of CT and MRI images. I want to perform NSST on both CT and MRI images to get high pass and low pass coefficients. is there any matlab code available for performing NSST on an image to get low pass and high pass coefficients? I want to perform separate operations on the decomposed low pass and high pass coefficients separately. please help.

hi,you can get nsst_toolbox in github, such as WeiTan1992/NSST-MSMG-PCNN: Code for "Multi-modal medical image fusion algorithm in the era of big data" (github.com)

this code included the toolbox,it may be what you want, best wishes.
