This is a Matlab implementation of the I-divergence approach to shape from defocus [1, Chapter 5].
The algorithm is broken down into several M files, which can be used in isolation or replaced. 
The source code is available as is and only for research purposes (see comments at the beginning 
of each file).

To test the software, run iDivergence.m in a Matlab console window and then follow the instructions.
