Preamble

This project is the result of a course of Image Processing for Computer Graphics offered at IMPA.

The work consists of choosing a paper with an image processing technique and implement it, extending the basic technique by adding variation to achieve a particular effect and create a set of non-trivial examples and produce an expressive demonstration. The paper chosed was Edge Suppression by Gradient Field Transformation Using Cross-Projection Tensors by Amit Agrawal, Ramesh Raskar & Rama Chellappa.

Description

In this work, we implement the technique described in the paper with a different programming language (under a Free Software license) and with a GUI for easy parameter manipulation. We also extend the original technique to do image combining and achieving artistic effects by applying the technique just to some color channels.
