Claim One:
1. An image processing system, the system comprising: an input signal conveying information associated with an element of the image; one or more processors configured to encode the information in a pattern of relative pulse latencies communicated via a plurality of channels; and a filter configured to provide a generator signal based on the input signal such that: 
 g ( t )= LM∫∫S ( x,t−s ) F ( x,s ) dxds, where g(t) represents the generator signal as a function of time, L represents an image luminance, M represents an image contrast, S(x, t−s) represents a feature in the image as a function of space and time, and F(x, s) represents a filter kernel as a function of space and time; wherein the pattern of relative pulse latencies is insensitive to one or both of the image contrast or the image luminance.
