Environment

Run in MATLAB. Tested in MATLAB 2019b .

How to run

You can run the following files.

• demo1.m : Demo 1 -- Image Smoothing and Edge Preserving
• demo2.m : Demo 2 -- Image Denoising
• demo3.m : Demo 3 -- Image Colorization

Result images will be saved after processing.

Results

Demo 1 -- Image Smoothing and Edge Preserving

Demo 2 -- Image Denoising

Demo 3 -- Image Colorization

Todo

• In demo 1, speed of SW-MED is too slow. It should be accelerated.

• In demo 3, why does max operator work and min operator not work? I think it's wrong. If you know why, you can give me suggestions.

• In demo 3 code csig = c_var*2; , if set 0.6, original algorithm has a good performance. What does it affect?
