# Image processing

[![Build Status](https://travis-ci.com/hdl-util/image-processing.svg?branch=master)](https://travis-ci.com/hdl-util/image-processing)

SystemVerilog code for image processing tasks like [demosaicing](https://en.wikipedia.org/wiki/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](https://hdlmake.readthedocs.io/en/master/), you can add this repository itself as a remote module.

1. Other helpful modules are also available in this GitHub organization.

1. Consult the testbench in `test/malvar_he_cutler_demosaic_tb.sv` for example usage.

1. Read through the parameter descriptions in `malvar_he_cutler_demosaic.sv` and tailor any instantiations to your situation.

1. Please create an issue if you run into a problem or have any questions.

## To-do List

* [x] [Malvar-He-Cutler](https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/Demosaicing_ICASSP04.pdf) demosaic algorithm

* [ ] More upon request
