New tool for virtual and augmented reality uses ‘deep learning’

by Chiho Choi | Jun 22, 2016 | Ayan Sinha, Chiho Choi, Karthik Ramani, News

WEST LAFAYETTE, Ind. – Future systems that allow people to interact with virtual environments will require computers to interpret the human hand’s nearly endless variety and complexity of changing motions and joint angles. In virtual and augmented reality, the...

DeepHand: Robust Hand Pose Estimation by Completing a Matrix Imputed with Deep Features

by Chiho Choi | Jun 21, 2016 | 2016, Ayan Sinha, Chiho Choi, Karthik Ramani, Recent Publications, Shape Understanding

We propose DeepHand to estimate the 3D pose of a hand using depth data from commercial 3D sensors. We discriminatively train convolutional neural networks to output a low dimensional activation feature given a depth map. This activation feature vector is...
