Abstract Most modern hand pose estimation methods rely on Convolutional Neural Networks (CNNs), which typically require a large training dataset to perform well. Exploiting unlabeled data provides a way to reduce the required amount of annotated data. We propose to take advantage of a geometry-aware representation of the human hand, which we learn from multi-view images without annotations. The objective for learning this representation is simply based on learning to predict a different view. Our results show that using this objective yields clearly superior pose estimation results compared to directly mapping an input image to the 3D joint locations of the hand if the amount of 3D annotations is limited. We further show the effect of the objective for either case, using the objective for pre-learning as well as to simultaneously learn to predict novel views and to estimate the 3D pose of the hand.
