- 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.
