Abstract

We present a simplified dual-channel discrimination model with spatio-temporal filters to represent the visual system contrast sensitivity, and masking based on local spatio- temporal contrast energy. The contrast sensitivity filter parameters of the model were based on previous work. The masking and global sensitivity parameters are calibrated to masking data using brief grating target signals masked by a 700 msec grating with the same spatial parameters.
