Colour Edge Filtering

The chromavec library implements a set of filters that can perform edge detection directly on RGB images without first having to go through an RGB to greyscale conversion. This document provides information about the library and the underlying theory. The goal is to go from an RGB image such as this

to an edge map

without any colour to grey conversions.

The code accompanying this document is available on Github.
