"The broad region outside the classical receptive field (CRF) of a neuron in the primary visual cortex (V1), namely non-CRF (nCRF), exerts robust modulatory effects on the responses to visual stimuli presented within the CRF. This modulating effect is mostly suppressive which plays important roles in visual information processing. One possible role is to extract object contours from disorderly background textures."

The broad region outside the classical receptive field (CRF) of a neuron in the primary visual cortex (V1), namely non-CRF (nCRF), exerts robust modulatory effects on the responses to visual stimuli presented within the CRF. This modulating effect is mostly suppressive which plays important roles in visual information processing. One possible role is to extract object contours from disorderly background textures. In this study, a two-scale based contour extraction model, inspired by the inhibitory interactions between CRF and nCRF of V1 neurons, is presented. The kernel idea is that the side and end subregions of nCRF work in different manners,...
