This paper proposes a human face shape matching based on shape context useing shape context algorithm. In the shape matching of the two targets similarity comparison,the focus of this approach is to use the shape context algorithm to calculate log-polar coordinate histogram Cost value,the calculation of similarity to the pre-set thresholds to determine whether his face matcheds. Experimental results show that the algorithm in two-dimensional targets in the invariance has accurate matching results
