A New Approach to Structure Preserving Feature Extraction.
Scott A. Starks, De Figueiredo,Rui J P · Defense Technical Information Center (DTIC) · 1977
This paper presents an approach to nonlinear feature extraction based on certain graph theoretical considerations (such as the minimal spanning tree, maximally complete subgraphs, inconsistent edges and diameter edges) and topological considerations (such as interpoint distance measures). After appropriate introductory sections, the feature extraction algorithm is developed. The algorithm is hierarchical in nature and offers considerable savings in terms of computer computation and storage requirements. An outline of the computer procedure is also included. (Author)
