Query: Real-time Pose and Shape Reconstruction of Two Interacting Hands With a
  Single Depth Camera   We present a novel method for real-time pose and shape reconstruction of two
strongly interacting hands. Our approach is the first two-hand tracking
solution that combines an extensive list of favorable properties, namely it is
marker-less, uses a single consumer-level depth camera, runs in real time,
handles inter- and intra-hand collisions, and automatically adjusts to the
user's hand shape. In order to achieve this, we embed a recent parametric hand
pose and shape model and a dense correspondence predictor based on a deep
neural network into a suitable energy minimization framework. For training the
correspondence prediction network, we synthesize a two-hand dataset based on
physical simulations that includes both hand pose and shape annotations while
at the same time avoiding inter-hand penetrations. To achieve real-time rates,
we phrase the model fitting in terms of a nonlinear least-squares problem so
that the energy can be optimized based on a highly efficient GPU-based
Gauss-Newton optimizer. We show state-of-the-art results in scenes that exceed
the complexity level demonstrated by previous work, including tight two-hand
grasps, significant inter-hand occlusions, and gesture interaction.
