1. A method for determining statistical data for pixels of an image, the pixels having a higher bit depth per band, wherein the higher bit depth per band comprises greater than 8 bits per band, the method being implemented by a computer system that includes one or more processors configured to execute computer program modules, the method comprising:
dividing, by the one or more processors, the image having pixels with the higher bit depth per band into a plurality of image sections, each image section in the plurality of image sections having a polygonal shape and including substantially homogenous features, wherein at least two image sections in the plurality of image sections have different polygonal shapes defining different area sizes, each image section comprising a plurality of pixels and each pixel having a plurality of bands and a bit depth greater than 8 bits per band; computing, by the one or more processors, statistical data for pixels within each polygonal image section, the statistical data comprising histograms of each band of each pixel within each polygonal section; storing, by the one or more processors, data of each polygonal image section with the image in a storage medium; and storing, by the one or more processors, the statistical data for pixels within each polygonal image section with the data of each corresponding polygonal image section in the storage medium. |
