Systems Methods in Visual Modelling

Models of visual processing in living systems can be successfully developed for the front end sensorial part, which in vertebrates correspond to the retina. The appropriate modelling tools are the tools of classical systems theory. In this line, we present first analytical models for the frog's retina and for higher vertebrate retinae, leading to the generalized structure of receptive fields processing for modelling linear and non-linear behaviour. Next, transformations on input data receptive fields are presented, including the novel concept of micro-structures of retinal receptive fields in form of Newton Filters, the concepts of transformation on input and output spaces and the concepts of transformation on receptive fields by means of partitions.
