Abstract

The general problem of precise position estimation is analyzed in the context of quantization errors. A formalism referred to as the locales approach to geometric precision is reviewed. A lower bound on position estimation uncertainty due to quantization is discussed. Some simulation results for an optimal position estimation algorithm, referred to as position decoding, are presented. A heuristic development of an image geometric fidelity measure is presented.
