In this paper, we strive to answer two questions: What is the current state of 3D hand pose estimation from depth images? And, what are the next challenges that need to be tackled? Following the successful Hands In the Million Challenge (HIM2017), we investigate the top 10 state-ofthe-art methods on three tasks: single frame 3D pose estimation, 3D hand tracking, and hand pose estimation during ...

This article presents a mathematical framework to simultaneously tackle the problems of 3D reconstruction, pose estimation and object classification, from a single 2D image. In sharp contrast with state of the art methods that rely primarily on 2D information and solve each of these three problems separately or iteratively, we propose a mathematical framework that incorporates prior “knowledge”...

This paper describes a novel compact representation of local features called the tensor doublet. The representation generates a four dimensional feature vector which is significantly less complex than other approaches, such as Lowe’s 128 dimensional feature vector. Despite its low dimensionality, we demonstrate here that the tensor doublet can be used for pose estimation, where the system is tr...

Robotic handling of objects requires exact knowledge of the object pose. In this work, we propose a novel vision system, allowing robust and accurate pose estimation of objects, which are grasped and held in unknown pose by an industrial manipulator. For superior robustness, we solely rely on object contour as a visual cue. We address the apparent problems of object symmetry and ambiguous persp...

In this paper, we propose a novel method for generating 3D line segment based model from an image sequence taken with a RGB-D camera. Constructing 3D geometrical representation by 3D model is essential for model based camera pose estimation that can be performed by corresponding 2D features in images with 3D features of the captured scene. While point features are mostly used as such features f...

This survey reviews advances in human motion capture and analysis from 2000 to 2006, following a previous survey of papers up to 2000 [206]. Human motion capture continues to be an increasingly active research area in computer vision with over 300 publications over this period. A number of significant research advances are identified together with novel methodologies for automatic initializatio...

This paper proposes a method for automatically constructing triangular G 1 spline models of complex three-dimensional objects from a few registered photographs. These models are used for pose estimation from monocular silhouette data and they form the basis for a simple recognition strategy. The proposed approach is demonstrated by several experiments.

This paper addresses the problem of estimating and tracking human body keypoints in complex, multi-person video. We propose an extremely lightweight yet highly effective approach that builds upon the latest advancements in human detection [15] and video understanding [5]. Our method operates in two-stages: keypoint estimation in frames or short clips, followed by lightweight tracking to generat...

Both the original version of David Lowe's innuential and classic algorithm for tracking known objects and a reformulation of it implemented by Ishii et al. rely on (diierent) approximated imaging models. Removing their simplifying assumptions yields a fully pro-jective solution with signiicantly improved accuracy and convergence, and arguably better computation{ time properties.

State-of-the-art human pose estimation methods are based on heat map representation. In spite of the good performance, the representation has a few issues in nature, such as not differentiable and quantization error. This work shows that a simple integral operation relates and unifies the heat map representation and joint regression, thus avoiding the above issues. It is differentiable, efficie...
