Scoliosis Avatar Dataset: De-identified Silhouette Images for Markerless Lumbar Asymmetry Analysis

This dataset contains de-identified X-ray-derived avatar silhouette images and representative sample output images used to support the study “A Signal-Based Quantification Framework for Waist Asymmetry from Posterior Trunk Images.” The avatar images were generated from de-identified scoliosis-related radiographic cases and were prepared to represent posterior trunk morphology in a privacy-preserving form. The dataset is intended to support reproducibility of the contour-based waist asymmetry analysis framework described in the associated manuscript. Raw posterior clinical photographs and original clinical imaging data are not included in this dataset due to privacy and ethical restrictions. Only de-identified avatar images and representative analysis outputs are provided.
