Query: Learning to Disambiguate Strongly Interacting Hands via Probabilistic
  Per-pixel Part Segmentation   In natural conversation and interaction, our hands often overlap or are in
contact with each other. Due to the homogeneous appearance of hands, this makes
estimating the 3D pose of interacting hands from images difficult. In this
paper we demonstrate that self-similarity, and the resulting ambiguities in
assigning pixel observations to the respective hands and their parts, is a
major cause of the final 3D pose error. Motivated by this insight, we propose
DIGIT, a novel method for estimating the 3D poses of two interacting hands from
a single monocular image. The method consists of two interwoven branches that
process the input imagery into a per-pixel semantic part segmentation mask and
a visual feature volume. In contrast to prior work, we do not decouple the
segmentation from the pose estimation stage, but rather leverage the per-pixel
probabilities directly in the downstream pose estimation task. To do so, the
part probabilities are merged with the visual features and processed via
fully-convolutional layers. We experimentally show that the proposed approach
achieves new state-of-the-art performance on the InterHand2.6M dataset. We
provide detailed ablation studies to demonstrate the efficacy of our method and
to provide insights into how the modelling of pixel ownership affects 3D hand
pose estimation.
