New Findings from University of Costa Rica in the Area of Information Technology Described (Hand shape identification on multirange images)

July 8, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Investigators discuss new findings in Information Technology. According to news reporting originating from San Jose, Costa Rica, by VerticalNews correspondents, research stated, "A hand-shape based biometric identification system which is independent of the image spectrum range is proposed here. Two different spectrum ranges; visible and mid-range infrared, were used to validated the architecture, which maintained the accuracy and stability levels between ranges."

Our news editors obtained a quote from the research from the University of Costa Rica, "In particular, three public databases were tested, obtaining accuracies over 99.9% using a 40% hold-out cross-validation approach. Discrete Hidden Markov Models (DHMM) representing each target identification class was trained with angular chain descriptors. A kernel was then extracted from the trained DHMM and applied as a feature extraction method."

According to the news editors, the research concluded: "Finally, supervised Support Vector Machines were used to classify the extracted features."
