摘要Owing to the variations including both intrinsic and extrinsic factors, age estimation remains a challenging problem. In this paper, five cascaded structure frameworks are proposed for age estimation based on Convolutional Neural Networks (CNN). All frameworks are learned and guided by auxiliary demographic information, since other demographic information (i.e. gender and race) is beneficial for age prediction. Each cascaded structure framework is embodied in a parent network and several subnetworks. For example, one of the applied framework is a gender classifier trained by gender information, and then two sub-networks are trained by the male and female samples, respectively. Furthermore, we use the features extracted from the cascaded structure frameworks with Gaussian process regression (GPR) that can boost the performance further for age estimation. Experimental results on the MORPH II and CACD datasets have gained superior performances compared to the state-of-the-art methods. The mean absolute error (MAE) is significantly reduced from 3.63 to 2.93 years under the same test protocol on the MORPH II dataset.
