We propose a fully convolutional conditional generative neural network, the latent transformation neural network, capable of rigid and non-rigid object view synthesis using a lightweight architecture suited for real-time applications and embedded...

Learning Hand Articulations by Hallucinating Heat Distribution

Learning Hand Articulations by Hallucinating Heat Distribution

Chiho Choi, Sangpil Kim, Karthik Ramani
Proceedings of the IEEE International Conference on Computer Vision, 3104-3113

We propose a robust hand pose estimation method by learning hand articulations from depth features and auxiliary modality features. As an additional modality to depth data, we present a function of geometric properties on the surface of the hand...
