Recognition of 3D tracks in sign language gesture by Procrustes analysis

Abstract

As for the research of recognition of 3D tracks of objects, both techniques and concrete application examples are extremely few compared with that of 2D tracks which have many practical applications such as online character recognition. To overcome this problem, we previously examined the recognition of the sign language operation using Procrustes analysis. Procrustes analysis is a technique to compare two ordered data under various linear transformations. There are only several applications of Procrustes analysis in pattern recognition though it has a great advantage in flexibility to pattern deformation. This paper describes a method to give some solutions of the problems in symmetrization of the recognition function and in generation of the standard pattern. An experiment is conducted and the result shows the effectiveness of our proposed method.
