<p>An image (10), of the type that is comprised of an array of pixels (P1, P2), is filtered by the steps of: (a) reading a respective group (G1, G2) of pixels from the array for each individual pixel (P1, P2, ...) that is in the array, with each pixel group overlapping other pixel groups and consisting of pixels that are contiguous with the individual pixel; (b) quantizing (via module 20) each of the respective groups of pixels; (c) retrieving from a memory (30), a single pixel (40-1, 40-2) for each quantized group (I1, I2, ...) of pixels, with the single pixel being the result of a pre-performed transformation on the quantized group of pixels; and (d) concatenating (via 40) the retrieved pixels to form the filter image.</p> |
