Feature Extraction (Pattern Detection) Methods in Pattern Recognition
R. G. S. Asthana, Biswa Nath Chatterji · IETE Journal of Research · 1973
In this paper applications of pattern recognition are discussed in brief and a few methods of feature extraction are reviewed. A sequential algorithm is introduced which selects strategies for on line procedure and serves to guide for best feature subsets depending upon features already extracted.The method detects only a minimum number of feature subsets to detect the presented pattern from other categories and is capable of deriving invariant features from continuous patterns irrespective of size, slight orientation and deformation.
