What does this program do?

Fusion is an image fusion software for MS-Windows. It is used for fusing two images into one, while attempting to best preserve the information from each image. To understand what can be expected from the program, please see the examples further down the page.

What can I use it for?

For example:

Ok, so where can I get this program?

Version can be downloaded from right here! Please read the terms of usage before you download. The program has been tested on a WinXP system, but should work on any NT station. It supports 8bit and 24bit BMP images.

Who wrote this and why?

This program is a workshop project submitted by Alon Barnea as part of his studies for a BA in Computer Science degree at the Academic College of Tel-Aviv Yaffo. The project was performed under the supervision of Tal Hassner.

More information on the algorithm:

Fusion is an implementation of the algorithm originally described in the paper

Peter J. Burt & Raymond J. Kolczynski; "Enhanced Image Capture Through Fusion", ICCV 1993 pages 173 - 182.

Please see the original text for details. It has been claimed that this algorithm is imperfect, producing "halo artifacts". We believe these artifacts are the result of faulty implementations of the algorithm (e.g., gradient misalignments). We have seen no evidence of such artifacts in results produced by the software available here (see some examples below).

Picture fusion

The IDF- IR images, the leopard, and "Cramming" examples were all taken from the "Introduction to Computer and Biological Vision" course home page at the Weizmann Institute of Science.

The Library near-IR filtered images were taken from the "Alignment of Non-Overlapping Sequences" project web page, courtesy of Yaron Caspi and Michal Irani.

The "Picture fusion" images were taken from the MATHWORKS site.

The clock images were taken from Metapix.
