Abstract

Many biological visual systems have demonstrated that a large degree of image preprocessing takes places at the detector level, making effective use of the spatial arrangement of the detectors that are relatively sparsely interconnected. More sophisticated image processing is then performed in the visual cortex of the brain. Similarly, the aim of many recent work in active pixel sensors (APS) is thus to perform certain image preprocessing steps that can be more efficiently achieved at the detector level using analog circuitry, taking advantage of the parallelism of the image detectors. Its output is then sent to post-processors, often taking the form of digital signal processors.
