A Spatial Median Filter for noise removal in digital images

An implementation of J. C. Church, Yixin Chen and S. V. Rice, "A Spatial Median Filter for noise removal in digital images," IEEE SoutheastCon 2008, 2008, pp. 618-623, doi: 10.1109/SECON.2008.4494367.

Todo

General

• Folder for source images
• Folder for loaded./preprocessed images
• Function for distorting images
• Folders for distorted images (matrix), grouped based on distortion level
• Folders for reconstructed images (matrix), grouped based on distortion level and filter
• Reconstructed images visualize into image files as examples placed in a folder.
• Functions for each of the filter
• Function for RMSE calculation
• Functions for statistical analysis and visualization of RMSE (could be very case by case)
• Three major graphs in that paper: which mask size is good, which T level is good, and finally which filter is good

Filters

• mean filter
• simple median filter
• component median filter
• vector median filter

next

• spatial median filter
• modified spatial median filter
• Fix median filter to use magnitude
• Update mean, median filters to work with new make_mask
• Describe Mean, Median filters + make_mask (pictorially?)
