An important requirement for successful gait recognition is robustness to variations including different lighting conditions poses and walking speed. Deformation of the gait silhouette caused by objects carried by subjects also has a significant effect on the performance of gait recognition systems a backpack is the most common of these objects. This paper proposes methods for eliminating the effect of a carried backpack for efficient gait recognition. We apply simple recursive principal component analysis PCA reconstructions and error compensation to remove the backpack from the gait representation and then conduct gait recognition. Experiments performed with the CASIA database illustrate the performance of the proposed algorithm. Copyright 2009 Heesung Lee et al.

Introduction Gait recognition is the identification of individuals based on their walking style 1 . The theoretic foundation of gait recognition is the uniqueness of each person s gait as revealed by Murray et al. in 1964 2 . Gait analysis has the advantage of being noninvasive and noncontact. Gait is also less likely to be .
