Accordingly, I upvoted both the question and answer and want to give a little something, such as it is, back to the site. The basic idea is to use a simple digital version of the ...


My personal feeling is that you should do each things separately and compare the results. For example, take your MRI dataset and denoise using "standard algorithm 1", "standard algorithm 2" and "neural network algorithm 1". I would keep things reasonably simple unless you have a good justification of doing "standard algorithm 2 and neural network algorithm ...
