1. An automated method for finding regions of interest in an image comprising: computing a texture value associated with the spectral features for a plurality of sub-blocks of an image, the texture value computed on at least one of the color bands for each of the sub-blocks; determining an information value associated with each of the plurality of sub-blocks; and automatically grouping sub-blocks together that have an information value that resides in a predetermined range to form a region of interest, wherein the two neighboring sub-blocks are combined into a new group only if the area of either of the two sub-blocks is greater than a bounding box area of either of the two sub-blocks multiplied by a predetermined non zero threshold.
