Research Paper
Core Innovation
This paper introduces Learnable SMPLify, which replaces the slow iterative optimization in traditional SMPLify with a single-pass neural regression model. It uses a novel temporal sampling strategy and human-centric normalization with residual learning to enhance generalization and speed. This approach achieves nearly 200 times faster runtime while maintaining accuracy and can integrate with existing image-based estimators.

Research Paper Overview
Learnable SMPLify: A Neural Solution for Optimization-Free Human Pose Inverse Kinematics
Summary
This paper proposes Learnable SMPLify, a neural network framework that replaces the iterative optimization process in SMPLify for 3D human pose and shape estimation with a single-pass regression model. It introduces a temporal sampling strategy for training data construction and a human-centric normalization scheme with residual learning to improve generalization. The method achieves nearly 200x faster runtime, generalizes well to unseen datasets, and can be used as a plug-in to refine existing image-based estimators.
