Local Deep Neural Networks for gender recognition

•A new model, called Local-DNN, is proposed for the gender recognition problem.•The model is based on local features and deep neural networks.•The local contributions are combined in a voting scheme for the final classification.•The model obtains state-of-the-art results in two wild face image datasets.

Deep learning methods are able to automatically discover better representations of the data to improve the performance of the classifiers. However, in computer vision tasks, such as the gender recognition problem, sometimes it is difficult to directly learn from the entire image. In this work we propose a new model called Local Deep Neural Network (Local-DNN), which is based on two key concepts: local features and deep architectures. The model learns from small overlapping regions in the visual field using discriminative feed-forward networks with several layers. We evaluate our approach on two well-known gender benchmarks, showing that our Local-DNN outperforms other deep learning methods also evaluated and obtains state-of-the-art results in both benchmarks.
