Psychtoolbox:PsychDemos:GPGPUDemos

Demos for use of GPGPU computing with Psychtoolbox.

These demos illustrate use of massively parallel computing hardware,
mostly modern graphics processing units (“GPU”s) for general purpose
computation (“GP”) in the context of stimulus presentation.

Current demos require a NVidia CUDA compute capable GPU and installation
of the free and open-source GPUmat toolbox for Matlab.

GPUFFTDemo1 - Demonstrates a GPU accelerated 2D-FFT for image
filtering of a static image. This is a benchmark.

GPUFFTMoviePlaybackDemo - Use GPU accelerated FFT for filtering of a
live playing movie.

GPUFFTVideoCaptureDemo - Use GPU accelerated FFT for filtering of a live
video feed.
