Shearlet transform for image decomposition

Can anybody provide any idea regarding image decomposition in higher frequency and lower frequency using SHEARLET transform alongwith codes?

Hi Ankan,

Starting from MATLAB R2019b, the “sheart2” function can be used to return the Shearlet transform of a real-valued 2D image. The Shearlet transform can be specified by creating an “shearletSystem” object and adjusting the properties. You can refer to the documentation of the function for more details:

You can also check out ShearLab, a library developed specifically for processing images with shearlets at the following link:

Hope this helps!
