Hi, I am trying to generate some ground truth (Label) image for developing a deep learning algorithm to reduce the noise and enhancement simultaneously. However, some parts of the image are really affected by noise and artifacts. Please can you suggest to me what is the best way to normalize the image. I have previously applied median/mean/gaussian filtering, BM3D, NLM denoising approach. Please find the attached for a sample of image.

For normalizing, try rescale() or mat2gray().
For denoising, I'm sure those techniques you tried should have worked.
For more image denoising methods, see the book:
