Local phase quantization (LPQ) descriptor, first introduced by Ojansivu and Heikkila (2008), has successfully been applied in face recognition systems. In this paper, we combine local intensity area descriptor (LIAD), which was first introduced by Tran (2017), with LPQ descriptor to develop robust face recognition systems using LPQ descriptor. Face images were first encoded by LIAD as a noise and dimensionality reduction step. After that, the resulting images were presented through LPQ as a feature extraction step. A nearest neighbor method with chi-square measure is used in classification. Two famous datasets (the ORL Database of Faces and FERET) were used in experiments. The results confirmed that our proposed approach reached mean recognition accuracies that are 0.17\% ÷ 7.7\% better compared to five conventional descriptors (LBP, LDP, LDN, LTP, and LPQ).
