Abstract
Detection of moving targets in nature is an important problem inneuroscience. In freshwater turtles, it is believed that thevisual cortex performs this job. In this paper, a set of 'movingfishes' are considered and the visual data is compressed using aset of spatial basis functions. Input to the model cortex is thiscompressed visual data, and the associated cortical response isgenerated. This paper illustrates the role of dynamic motionreconstruction in a natural scene from the cortical activity wavesusing a bank of autoregressive moving average processors.
