ABSTRACT:
A system and method comprise defining a current rectangular region of the image bitmap, quantifying spectral characteristics of the current rectangular region, dividing the current rectangular region into four rectangular sub-regions in response to the spectral characteristics being greater than a predetermined threshold value, tagging the current rectangular sub-region as a terminal rectangular region in response to the spectral characteristics being less than or equal to the predetermined threshold value, tagging each rectangular sub-region as a terminal rectangular region in response to a size of the rectangular sub-region being less than or equal to a predetermined threshold size, defining one of the non-terminal rectangular sub-regions as the current rectangular region and repeating the above until all rectangular regions are tagged terminal, and determining color characteristics for each of the terminal rectangular regions.
