Abstract:
1. A method of processing a digital image, comprising the steps of: providing digital data indexed to represent positions on a display, said digital data being indicative of an intensity value I adjusting said intensity value for said each position in each i-th spectral band to generate an adjusted intensity value for said each position in each i-th spectral band in accordance with where S is the number of unique spectral bands included in said digital data and, for each n, W n is a weighting factor and F n (x,y) is a unique surround function applied to said each position (x,y) and N is the total number of unique surround functions; filtering said adjusted intensity value for said each position of said image in each of said S spectral bands using a filter function wherein a filtered intensity value R selecting a maximum intensity value V
