Abstract :
A new system is proposed for gait analysis and recognition applications. The new system is based on a denoising process and a new angular transform that are applied on binary silhouettes. Each human silhouette in a gait sequence is transformed into a low dimensional feature vector consisting of average pixel distances from the center of the silhouette. The sequence of feature vectors corresponding to a gait sequence is used for identification based on a minimum-distance criterion between test and reference sequences. By using the new system on the gait challenge database, improvements in recognition performance are seen in comparison to other methods of similar or higher complexity.
