Patent ID: 7848567

Claim:
A method for finding regions of interest in a synthetic image comprising: generating a plurality of sub-blocks for a plurality of synthetic images; computing a texture value derived from one or more color features associated with the plurality of sub-blocks, the texture value computed on at least one of one or more color bands for each of the sub-blocks, the texture value being computed using discrete cosine transform; computing a color value associated with the color value of each of the plurality of sub-blocks for one or more of the color bands, wherein the color value includes computing a color correlogram on one of one or more of the color bands for each of the sub-blocks in each of the synthetic images; determining an information value based on a weighted average of the texture value and the color value of each of the plurality of sub-blocks; and automatically grouping the sub-blocks based on the informational value to form a region of interest, wherein grouping includes grouping neighboring sub-blocks together that have an information value that resides in a predetermined range, wherein the grouped neighboring sub-blocks have a density that does not exceed an average density of the plurality of sub-blocks.
