The problem of 2D-Gabor filter is very slow. So some filters are proposed such as Separable Gabor fitler and WSSG filter. However, these filters are alos slow in the embedded systems that have no floating-point unit. So we propose using LUT for WSSG filter instead of multiplication operations with floating point numbers. This filtering consumes approximately 25 time faster than the normal WSSG fitlering with compareble enhancement results.
