Gauge figure task

This psychophysical method can be used to quantified pictorial relief (the perceived surface depth profile). The PsychToolbox (Matlab) software for doing the gauge figure task can be found here.

For long I have wanted to make a processing version. I changed it a bit (especially the preparation program) but it works (download)! Please cite the original paper if you publish something based on either code:
