1. A method for storing data related to an image, the image being associated with statistical data, the method being implemented by a computer system that includes one or more processors configured to execute computer program instructions, the method comprising: unevenly dividing the image into a plurality of polygonal image sections based on a detection of substantially homogenous features delimiting each of the polygonal image sections, each polygonal image section having the substantially homogenous features and comprising a plurality of pixels, each pixel having one or more bands and a bit depth per band that is too high for displaying on a display screen, the statistical data comprising statistical data computed for each band of each pixel within each polygonal image section, the image being further divided into a plurality of quads such that each quad has boundaries that contains at least a portion of one of the plurality of polygonal image sections; organizing the image, the plurality of quads, and the plurality of polygonal image sections in a form of a hierarchical tree structure such that a root node corresponding to the image has a plurality of branches corresponding to the plurality of quads and a branch node of the tree structure corresponding to a quad of the plurality of quads has two or more leaf nodes, each leaf node corresponding to a polygonal image section of the plurality of polygonal image sections; and storing the statistical data and the form of the hierarchical tree structure.
