Robust tagging in strange circumstance

AbstractThis paper aims to propose a new scheme for robust tagging for landmark definition in unknown circumstance using some qualitative evaluations based on orientation code representation and matching, which has been proposed for robust image registration even in the presence of changes in illumination and occlusion. The necessary characteristics for effective tags include richness, similarity, and uniqueness, and are considered in order to design an algorithm for tag detection. These qualitative considerations can be utilized to design a simple and robust algorithm for tag definitions in combination with the robust image registration algorithm. © 2006 Wiley Periodicals, Inc.
