MPII Human Pose Models

Introduction

This work considers the task of articulated human pose estimation of multiple people in real world images. We propose an approach that jointly solves the tasks of detection and pose estimation: it infers the number of persons in a scene, identifies occluded body parts, and disambiguates body parts between people in close proximity of each other. This joint formulation is in contrast to previous strategies, that address the problem by first detecting people and subsequently estimating their body pose. We propose a partitioning and labeling formulation of a set of body-part hypotheses generated with CNN-based part detectors. Our formulation, an instance of an integer linear program, implicitly performs non-maximum suppression on the set of part candidates and groups them to form configurations of body parts respecting geometric and appearance constraints. Experiments on four different datasets demonstrate state-of-the-art results for both single person and multi person pose estimation.

Overview

Starting from a single monocular image of multiple individuals, a sparse set of body part detection candidates is computed (I). In order to incorporate various types of interactions between body parts within and across human bodies, a densely connected graph is constructed (II). The problem of multi-person pose estimation is then treated as integer linear program (ILP). Solution results into simultaneous partitioning of part detection candidates into person clusters and labeling each detection by one of the part classes (III), thus computing joint pose estimation of multiple people (IV).



DeeperCut improves over DeepCut on three fronts:

Qualitative Results

fully connected graph

joint partitioning and labeling

jointly estimated poses

Quantitative Results

DeeperCut significantly outperforms best known multi-person pose estimation results and demonstrates competitive performance on the task of single person pose estimation.
