Image-Based Relighting Framework is an open source GUI that implements three types of image-based relighting algorithms using reflectance data captured with either a light stage, a free-form acquisition or a regular room. It was implemented during my MSc thesis at Imperial College London in the Summer 2014. It is distributed under the LGPL license.

The framework implements the following papers :
- Acquiring the Reflectance Field of a Human Face, Paul Debevec, Tim Hawkins, Chris Tchou, Haarm-Pieter Duiker, Westley Sarokin, and Mark Sagar, SIGGRAPH 2000 Conference Proceedings
- The free-form light stage, Vincent Masselus, Philip Dutré, Frederik Anrys In Proc. EGWR, EGRW ’02, 247–256.

###Version Version 1.0
###Compilation This program has been compiled and tested both on Windows, Linux and MacOS environments. It requires the following libraries in order to compile :
- OpenCV (tested with version 2.4.11)
- Qt (tested with version 5.4.2)
A "IBR_Framework.pro" file is provided for compilation with QtCreator IDE. Please update the libraries paths to match your installation.
###Installation
The light stage data can be obtained on USC ICT website :
Please read appendix A of my MSc thesis for more information on how to setup the software.
####Environment mapping For the environment mapping to work you will have to download the latitude longitude maps of the environment. Some are available at the following links :
Create a folder called "environment_maps" in the directory where the program is compiled and name the environment maps as follows :
Environment | File Name |
---|---|
Grace Cathedral | grace_latlong |
Uffizi Gallery | uffizi |
St Peter's Basilica | stpeters_probe |
Pisa Courtyard | pisa_courtyard |
Eucalyptus Grove | eucalyptus_grove |
