Abstract :
Active resistor meshes, characterised by an inhomogeneous anisotropic pattern of local interconnections, present node voltage responses to current impulses at the nodes that efficiently emulate signal processing functions of visual cortex neurons, organised into orientation maps. Experiments with artificial and natural textured images validated the approach.
