On the basis of its importance both in theoretical research and practical application, gait recognition needs to be further studied. With the help of current research findings, this thesis has made the following innovative contributions: 1. Based on the perceptual shape descriptors and the eigenspace transformation, a new automatic gait recognition algorithm is proposed. The principal component analysis and the multiple discriminant analysis are used to reduce data dimensionality and to optimize the separability of different classes.
