Abstract

Gabor filtering is known as a function model of the primary visual cortex in the brain. It is also known as a powerful feature extraction method for image recognition. This paper presents an image processing system using the dedicated Gabor-filtering LSI that we have already developed based on a merged analog-digital architecture. The Gabor-filtering LSI is controlled by an FPGA connected with a personal computer and a camera. The developed system can successfully output a Gabor impulse response with even and odd functions, and also detect a stripe-pattern image with a given direction in real time.
