In this paper, we are particularly concerned about the increasing availability of Child Abuse Material. Therefore, we have explored alternatives to detect non-adults in visual content. Initially, different age estimations and underage detection techniques are reviewed by analyzing existing datasets. Finally, several local descriptors and Convolutional Neural Networks for underage detection are evaluated. The experimental results obtained for a large dataset that combines collections such as FG-Net, Adience, GenderChildren, The Image of Groups and Boys2Men evidence the complementary information contained in both local descriptors and neural networks, as their fusion boosts the accuracy of non-adult detection to over 93%.||URI:||http://hdl.handle.net/10553/42117||ISSN:||0167-8655||DOI:||10.1016/j.patrec.2017.03.016||Source:||Pattern Recognition Letters [ISSN 0167-8655], v. 113, p. 10-18|
