Abstract(in English) | It is known that simple cells in the primary visual cortex (V1) perform feature extraction by Gabor filtering of images from retinas. One of the reasons why humans have global vision functions is visual processing in a feature space based on Gabor filtering results, which include various spatial frequency information. However, because this filtering requires huge calculations, there exist few examples of its practical applications. We have developed a processor LSI that can achieve real-time Gabor filtering by pixel-parallel operation using merged analog/digital architecture. This paper reports the detail of the calculation model for the Gabor-filtering LSI and the results of evaluation of the LSI as a Gabor-filtering processor for mimicking V1 functions. |
