ISET is based on the MATLAB® programming environment and image processing toolbox.
The software package includes a Graphical User Interface (GUI), MATLAB® source code, data structures and many examples of program scripts.
Contact ImagEval to download a free demo version of ISET or to obtain a quotation.
The free demo version includes the GUI but not the MATLAB® source code.
Video introductions to the GUI can be found here.

ISET Scene data can be freely downloaded from the web.
