This software is freeware: You can use and distribute it as you like, but you must quote the adequate reference when publishing result obtained with one of the programs. Please make sure you have carefully read the corresponding papers before using the software or contacting me. All software is without any kind of guaranty, I take no responsibility for it, and your critical judgment of the results is always superior to my programming skills. Bug reports are welcome, though.

MGLINSTALLER Matlab DLLs If you don't have Matlab 6.0 installed, you will need this in order to run TFRD.

The remaining part here are addititional transformations for the VisionAnalyzer software and run under windows. To install them, copy the DLL in the directory where the VisionAnalyzer is installed. Then drag the file unto RegisterComponents.exe. Please DON'T contact the company for support related to the software downloaded here.
