Abstract: A new method was described for gait recognition by using moment invariants. The body contour represented in 2D signature was transformed into moment invariants represented in 1D signature. The gait sequences could be represented by using moment invariants vectors. The vectors were normalized and used to recognize the gait. The results of the experiments show that the method have an encouraging recognition performance.

Key words: gait recognition, contour representation, normalization moment invariants, spatio-temporal correlation
