One of the problems with a detail-in-context system is zooming into fat-pixels when one increases the magnification of the selected detail. The images below show an overpass in an aerial photograph being magnificed from 2x to 4x and finally to 8x. The fat pixels become an increasing problem.
My solution involves storing additional detail information in memory. This additional information is stored in such a way that it makes it easy to bring in the additional information as it is called for based on location and magnification of the lens that is looking into the information. The images below so the same overpass being magnified the same amounts using the Real Magnification algorithm.
