Pose-Driven Body Shape Prediction Algorithm Based on the Conditional GAN

Abstract

Reconstructing accurate human body shapes from clothed images remains a challenge due to occlusion by garments and limitations of the existing methods. Traditional parametric models often require minimal clothing and involve high computational costs. To address these issues, we propose a lightweight algorithm that predicts body shape from clothed RGB images by leveraging pose estimation. Our method simultaneously extracts major joint positions and body features to reconstruct complete 3D body shapes, even in regions hidden by clothing or obscured from view. This approach enables real-time, non-invasive body modeling suitable for practical applications. © 2025 by the authors.
