To solve the problem of insufficient feature extraction and sensitivity to the noise and illumination encountered using difference local directional pattern (DLDP) method, this article proposes a double difference local direction pattern (DDLDP) face feature extraction method. First, a 3×3 domain pixel gray value with a radius of 1 and a 5×5 domain pixel gray value with a radius of 2 were convolved with eight Kirsch template operators to obtain two groups of eight gray response values. Then, the gray-scale response value with a radius of 1 was obtained as a difference between the values of the neighboring pixels at both sides to obtain eight gray-scale response differences. Meanwhile, the edge response difference values of different radius were also calculated. Finally, the two sets of gray response differences were taken as absolute values, and their maximum absolute values correspond to the subscripts form DDLDP code. Simulation experiment results show that the proposed algorithm has better recognition effect than other single face recognition algorithms based on local directional pattern (LDP). The DDLDP algorithm can fully extract the facial features, and have better robustness to illumination and noise.
