Software

Disclaimer: All the codes below are provided as is. Please feel free to contact me for any questions/comments/suggestions. Unfortunately, I probably may not be able to reply each email.

Image Processing

• Superresolution: this is a demo code of SR using POCS. Here is a demo video.
  
• SCoBeP-SR: Superresolution with SCoBeP. Here is the paper describing the algorithm.
• Vehicle tracking software based on sparse coding

Communications/Coding

• Particle based belief propagation: this is a demo of particle based BP for channel noise and source correlation estimation
• Arithmetic Coder: this is a simple demo code I used for teaching arithmetic coding. It is in no way a productive code. Here is my short notes on arithmetic coding.
  
• Trellis Soft-Decoder: this is based on belief propagation (forward/backward algorithm). I use this to teach BP. I didn't compare it with other soft decoder. I think it should work as well as BCJR. Here is some notes describing it.
• LDPC/IRA: a demo code for me to teach LDPC. Running as a jupyter notebook.

Jupyter Notebooks for Teaching

• Linear regression with regularization
• LDPC/IRA example
• Inference example using belief propagation

Misc

• File Displayer: a simple Matlab tool to display a text file in a text box. I made it a while ago when I was still using Matlab 6. Maybe there are other commands to do the same thing now. I didn't check.
• Finite Field Toolbox: a toolbox for simple finite field operations.
