Age from Faces in the Deep Learning Revolution

In this study, we introduce an approach to classify gender and age from images of human faces which is an essential part of our method for autonomous detection of anomalous human behaviour. Human behaviour is often uncertain, and sometimes it is affected by emotion or environment. Automatic detection can help to recognise human behaviour which later can assist in investigating suspicious events. Central to our proposed approach is the recently introduced transfer learning. It was used on the basis of deep learning and successfully applied to image classification area. This paper is a continuous study from previous research on heterogeneous data in which we use images as supporting evidence. We present a method for image classification based on a pretrained deep model for feature extraction and representation followed by a CNN classifier. Because very few data sets with labels of gender and age exist of face images, we build one dataset named GA Face and applied our proposed method to this dataset achieving excellent results and robustness.
