Abstract:
1. A method of image processing, the method comprising: (a) calculating a first pixel color feature (PCF) value for each pixel in a color image to generate a set of PCF data; (b) applying two adaptive smoothing filters to said first PCF value, wherein the two adaptive smoothing filters have respective fine and coarse smoothing parameters, thereby determining two new PCF values for said first PCF value at each pixel in said color image; (c) differencing between said two new PCF values thereby producing a spatial adaptive bandpass filter (ABPF) for each pixel, whereby said different smoothing parameters define a degree of local contrast with respect to adjacent regions; and (d) enhancing and detecting the image regions having said degree of local contrast therebetween.
