核心概念
STRIDE proposes a novel approach for 3D pose estimation under occlusion, achieving robust and accurate results through test-time training.
要約
The article introduces STRIDE, a method for 3D pose estimation under occlusion.
Challenges in accurate prediction of human poses under severe occlusions are highlighted.
STRIDE utilizes Test-Time Training (TTT) to refine initial pose estimates into accurate and temporally coherent poses.
The method is model-agnostic and outperforms existing single-image and video-based pose estimation models.
Results demonstrate superior handling of substantial occlusions, achieving fast, robust, accurate, and temporally consistent 3D pose estimates.
Experiments conducted on challenging datasets like Occluded Human3.6M, Human3.6M, and OCMotion validate the efficacy of STRIDE.
Introduction:
Accurate 3D pose estimation is crucial for various applications like action recognition and virtual reality.
Challenges in Pose Estimation:
Traditional image-based estimators struggle with heavy occlusions due to a lack of temporal context.
Proposed Solution - STRIDE:
STRIDE is introduced as a novel Test-Time Training (TTT) approach for refining noisy initial pose estimates into accurate and temporally coherent poses.
Methodology:
STRIDE leverages a motion prior model pre-trained on 3D pose sequences to handle sequence-specific occlusion patterns not encountered during training.
Experimental Results:
Comprehensive experiments on challenging datasets demonstrate the superiority of STRIDE over existing methods in handling substantial occlusions.
