摘要：

Multiple channel models of visual function proposed to date have been either threshold models or suprathreshold models. The transition between detection and perception of contrast which involves the gradual disappearance of spatial response pooling has not been addressed. We propose a model that allows us to simulate contrast detection, contrast perception and the gradual disappearance of spatial response pooling with contrast. The model successfully predicts thresholds and perceived contrast functions for several multiple component stimuli.
