Image processing

SystemVerilog code for image processing tasks like demosaicing.

Why?

I implemented raw camera video playback, but wanted a place to keep the demosaic algorithm logic and share it with others.

Usage

1. Take files from src/ and add them to your own project. If you use hdlmake, you can add this repository itself as a remote module.
2. Other helpful modules are also available in this GitHub organization.
3. Consult the testbench in test/malvar_he_cutler_demosaic_tb.sv for example usage.
4. Read through the parameter descriptions in malvar_he_cutler_demosaic.sv and tailor any instantiations to your situation.
5. Please create an issue if you run into a problem or have any questions.
