Abstract :
In a typical scene situation, spatial frequency measures how frequently a pattern appears within a given distance and temporal frequency reveals how rapidly a pattern profile changes over time-both are the important properties of visual stimuli. However, spatial frequency may remain the same, temporal frequency may remain the same, yet temporal-order (a non-luminance stimuli property) may change, which in most cases implies scene interpretation (perceptual grouping) changes. We explore how non-luminance stimuli properties can be organized in time domain by the temporal gain of cell activities in the antagonistic retinal channels to manifest a time ordered feature map. In this approach cells have on/off receptive field profiles and their collective local behaviors become sensitized to recency information, so that local cell synapses are configured to incorporate time-space influences for an adaptive visual mask
