METHOD AND SYSTEM FOR PROCESSING AN IMAGE

Abstract: a method for processing an image comprising image data. the image data comprises pixel intensity values, said pixel intensity values being associated with respective pixel locations. for a plurality of zones of the image, based on a plurality of pixel intensity values in the respective zone of the image, a value of a characteristic pertaining to the plurality of pixel intensity values, is determined. at least a spatial filtering process is performed on data representative of the values of the characteristic for the plurality of zones, to obtain filtered values of an image characteristic at respective locations. the filtered values are interpolated from to determine a local value of the image characteristic at a said pixel location. the determining and/or the interpolating is performed using fixed function circuitry. the spatial filtering process is performed using a programmable processor.
