Abstract

We present a functional model of V4 area in visual cortex based on predictive coding scheme, in which the prediction is compared with three kinds of images corresponding to three kinds of image representations which are projected through the filters with three different sizes of spatial resolutions. The prediction is represented as a combination of elemental figures. These representations are generated by the response property of main neurons in V1 and V4 areas that the main neurons respond selectively to a limited band of frequencies of spatial brightness distribution. We propose the functional role of elemental figures in invariant perception of object form in visual cortex.
