That would depend on area of application. Could you formulate a more concrete question? E.g. whether the method in paper is well formulated, sufficiently validated, has promising results, etc.

I am writing a review paper about MRI denoising methods in Transform domain.I read in a previous review paper by J, Mohan (2014) that wavelet,curvelet and contourlet are in transform domain in Denoising MR images. I found out that researchers used wave atom,PCA,ICA,DCT and BM3D for denoising MR images. I want to be sure that Can I consider these methods in Transform domain or not? Thanks
