Abstract: Aiming at the problem that it is difficult for face age estimation to find features that accurately characterise face age changes, this paper proposes an asymmetric multi-period deep residual network face age estimation model. First, an asymmetric residual block is used to improve the feature extraction ability of the network model. Secondly, a multi-period residual structure is built to solve the optimisation problem caused by network deepening. Then, a shortcut connection that combines pooling and convolution is used to reduce the information loss of the shortcut layer. Finally, the age estimation method combining multi-classification and sequential regression is used to reduce the prediction error. Experimental results on three public datasets showed that the error (MAE/RMSE) of this model is reduced to 2.42/3.44, 3.38/4.69 and 5.17/7.34, respectively, which proved the effectiveness of the proposed algorithm.
