Abstract


Gait recognition aims to identify individuals by the manner in which they walk. The prime innovation in this paper is a simple yet effective method of modelling the lower limbs using spline curves. To start with, we extract the binary silhouette from the monocular images. The gait cycle is extracted by exploiting the periodic variance of the width vector of the silhouette. Then, the novel gait feature area under the lower limbs, modelled using a cubic spline curve, is computed for each of the silhouettes in a cycle. Later Discrete cosine Transform is applied to the feature vector to create a feature matrix. The method of Multi-scale principal component analysis (MSPCA) was adopted for dimensional reduction of feature matrix containing the area signals. Finally Neuro-fuzzy and the K-NN classifiers are used to classify the final feature vectors. Experimental results on the CASIA datasets A, B show that the best accuracy achieved using Neuro-fuzzy and K-NN classifier is 95% and 97.1% respectively.
