Abstract:
A computer-implemented method for retrieving an image object from a plurality of images, comprising the steps of:providing an image object color correlogram; providing a plurality of color values; selecting a distance value to be used as the distance between pixels, in the image object and in the plurality of images, to be evaluated for color value; analyzing said image object according to said color values and said selected distance value; determining in response to the analyzing step a probability of finding a pixel of a particular color value at said distance value from a pre-selected pixel of a pre-selected color value; entering said probability into the image object color correlogram; providing color correlograms for each of said plurality of images; and intersecting the image object color correlogram with correlograms of the plurality of images to produce an intersection result, wherein the image object is distinguished by the intersection result from the images which do not contain the image object.
