ChromAberFix (ICCV 2017)

This repository contains the code for the ICCV 2017 paper "Revisiting Cross-channel Information Transfer for Chromatic Aberration Correction" authored by Tiancheng Sun, Yifan Peng, and Wolfgang Heidrich. Project page

Getting Started

We use Matlab 2016 to implement the algorithm. In the code, we use the open source package mmx and a slightly modified version of im2col. You can find these packages in the folder util/. Please run the code build.m inside to initialize these packages.

Running the tests

We provide an example image taken from diffractive lens. You can use the code test.m to test the algorithm. The core concept is to transfer the information from green channel (which is less burry) to other channels.

We also provide a blind deconvolution version of the green channel (deconvolved using Normalized Sparsity Measure). You can toggle the variable use_blind in test.m to deblur the images.
