A menu-driven program is described that generates and displays fully textured i.e., 8-bit gray scale stimuli which have been used to study human texture perception. The stimuli are displayed on standard video monitors using commercial video-controller cards installed in an IBM PCAT. The program implements both double random staircase and constant stimuli procedures for obtaining threshold discrimination data and also allow similarity-rating data to be collected. Data in each of these formats can be analyzed and plotted. The program also produces files containing stimulus specifications corresponding to any chosen number of superimposed sinusoids, generates the specified stimulus with either a rectangular or gaussian window using the data in those files, and performs a monitor gamma-correction via look-up tables.
