Visual Stimulus Toolbox

VisualStimulusToolbox is a lightweight Matlab toolbox for generating, storing, and plotting visual stimuli related to vision and neuroscience research such as sinusoidal gratings, plaids, random dot fields, and noise.

VisualStimulusToolbox provides a number of classes for creating, plotting, and storing visual stimuli such as:

• DotStim: field of randomly drifting dots
• GratingStim: drifting sinusoidal grating
• PlaidStim: drifting plaid stimulus (composed of two sinusoidal gratings)
• BarStim: drifting bar stimulus
• PictureStim: stimulus made from a picture (BMP, CUR, GIF, HDF, ICO, JPEG, PBM, PCX, PGM, PNG, PPM, RAS, TIFF, XWD)
• MovieStim: stimulus made from a movie (AVI, MPG, MP4, M4V, MOV, WMV, MJ2, ASF, ASX)
• CompoundStim: stimulus made from a mixture of stimulus types listed above
• Save/load stimuli to/from binary files. Record AVI.
