A Syntax-Directed Method of Extracting Topological Regions from a Silhouette.

摘要

The objective of this research is to develop a preprocessing technique for decomposing pictorial data into its topological units and subunits so as to enhance any subsequent feature/primitive extraction. To enhance the later stages of perception implies that each topological unit and its subunits must be labeled in such a way as to reveal their relationship to the other topological units of the pattern. If the labeling can be standardized then the feature/primitive analysis, which is very application-oriented, can process the results of the preprocessor decomposition as desired. While the proposal for such a decomposition (called segmentation or region analysis) is not new, the concept of decomposition to reveal a pattern's intrinsic structure prior to and independent of feature/primitive analysis is new.
