Abstract
Convolution Neural Networks (ConvNets) have successfully improved the recognition performance for various facial characteristics such as age, head pose, gender and identity. A large labeled training set is one of the most important factors for its success. However, it is difficult to collect sufficient and complete training images in some domains such as age and head pose estimation, where the image labels are usually ordered numbers. Fortunately, there is a correlation among neighboring labels, which makes these tasks different from traditional classification. Based on this fact, we convert the label of each image into a discrete label distribution. In this paper, we propose a novel deep label distribution learning (DLDL) framework by minimizing a Kullback-Leibler divergence between the predicted and groundtruth label distributions.  DLDL effectively utilizes the correlation information among neighboring labels in both feature learning and classifier learning. Experimental results show that the proposed approach produces significantly better results than state-of-the-art methods for age estimation and head pose estimation, and is particular suitable when the training set is small.

Abstract: Touchless hand gesture recognition systems are becoming important in automotive user interfaces as they improve safety and comfort. Various computer vision algorithms have employed color and depth cameras for hand gesture recognition, but robust classification of gestures from different subjects performed under widely varying lighting conditions is still challenging. We propose an algorithm for dynamic hand gesture recognition that utilizes multiple sensors: depth, intensity and radar with a 3D convolutional neural networks (CNN)-based classifier. We interleave the multiple channels to build normalized spatio-temporal gesture volumes and train gesture classifiers on CUDA-capable NVIDIA GPUs using Theano. To reduce potential overfitting with limited training data and to improve the generalization capability of the classifier, we propose an effective online and offline spatio-temporal data augmentation method. Our algorithm results in the best performance on two challenging multi-modal dynamic hand gesture datasets compared to the existing approaches.
