: Explain the physical constraints (e.g., pixel intensity cannot be negative).

: Describe the weighting matrix used to prioritize certain data points.

: Look for a README.txt , main.m (MATLAB), or .py (Python) script. These often contain the mathematical formulas needed for your "Methodology" section.

: Detail the dictionary learning or wavelet transform used to reduce data redundancy.

: Define the limitation of current reconstruction methods (e.g., noise, artifacts, or speed).

: List the specific "weights" or "iterative" steps that make this version unique. 2. Methodology (The "NNSWIBR" Logic)

: Describe the source files found within the .7z archive (e.g., .mat , .csv , or raw image data).

: Explain how the NNSWIBR algorithm improves upon standard Sparse Representation or Back-Projection.
