Abstract
Abstract: When a photon impinges on the retina, the light signal is transduced into an electrical signal. Afterward, the electrical signal is conveyed in turn to lateral geniculate nucleus (LGN), visual cortex, inferior temporal cortex (ITC), prefrontal cortex (PFC), medial temporal lobe (MTL) and other brain areas, and thus we can perceive the visual world, recognise objects, identify our friends, analyse events, remember every happy time, and guide our actions toward specific objects. All these tasks are very tough challenges for current computers, so it essential to understand the biological visual system that can guide our research on computational vision. In this talk we discuss our recent work on computational modelling of the ventral path way. This is a further step of the recent MIT’s follow up to Hubel and Wiesel’s feed-forward hierarchy model published in 1959. We particularly considered the feedback process between the visual cortex and MTL that consolidates the memory and assists the visual recognition. Our preliminary experimental results on object recognition support our model. Surely, this model is general and can be adapted to model the dorsal path way for motion analysis.
