As I was getting to understand abt the CS and why l1 norm alone works and l2 norm doesnt work …
With my discussion with RV , he was talking abt using CS and PI together. The idea here is to use the PI to give an initial estimate image rather than using the zero filled Density corrected image as the initial estimate.
When I went through the abstracts I found a similar (I should say same) idea as part of the abstract ..
The abstract is here 01488 🙂
