Paper Abstract

Biological vision systems of higher life forms naturally divide space, time, and color domains into a relatively few bandpass components. In the spatial domain, the division is primarily into a low frequency bandpass channel and a high frequency bandpass channel. Wavelet analysis also divides input into low and high band representations. Chips originally designed to exploit filtering functionality of biological retinas can also be used to perform fast analog decomposition of imagery into subsequent vision wavelet components. These filtering concepts are presented in connection to previously developed retinal processors and compared to conventional wavelet filters. Although perfect reconstruction is not performed by biological systems, it is used here as a metric for measuring level of information corruption inherent in biological filter models.
