Picture Decomposition,Tree Data-Structures and Identifying Directional Symmetries and Node Combinations.

摘要

The general problem treated in this report is that of extracting structural information from an object in a scene. In particular, symmetries are used as another--in addition to the average intensity values--global coarse picture parameter subregion characteristic, of a picture that has been regularly decomposed to a dimensionally reduced subset. Regular decomposition is a procedure through which a picture is subdivided in a particular way, leading to a data structure representation of the information which preserves geometric and topological relationships among pixels or among aggregates of pixels (substructures) found in the original picture.
