首个面向孟加拉人群的头姿态数据集，填补南亚群体数据空白。
Bengal-HP_RU: A Dataset of Bengal People For Head Pose Estimation
- 基于维基媒体公开图片构建，自动化处理后人工校正标签。
- 包含12,894张带连续俯仰/偏航/翻滚角标注的图像，2,400张用于测试。
- 覆盖年龄、光照、遮挡等真实场景多样性，适合跨族群姿态估计研究。
现有头姿态数据集多以白人或东亚人群为主，南亚群体尤其是孟加拉人严重缺失。本文提出Bengal-HP_RU，首个面向孟加拉人群的公开头姿态数据集，包含12,894张标注有连续俯仰角、偏航角和翻滚角的图像。图像来自维基媒体公共资源，经自动化流程处理并人工校正标签。数据按上传者身份划分，避免数据污染，共得10,494张训练图与2,400张测试图，涵盖296名不同上传者。数据集在年龄、性别、遮挡、光照和背景等方面具有显著多样性，反映真实野外环境。数据集已公开发布于https://doi.org/10.17632/xbw9kr37jb.2。
原文摘要 · Abstract (English)
Existing head pose datasets predominantly feature subjects of Western or East Asian origin, leaving South Asian populations, particularly Bengali individuals, largely underrepresented. We introduce Bengal-HP_RU, the first publicly available head pose dataset centred on Bengali subjects, comprising 12,894 labelled head images annotated with continuous yaw, pitch, and roll values. Images were collected from Wikimedia Commons under free licences and processed through an automated pipeline followed by manual label correction. The dataset is partitioned by Wikimedia uploader identity to prevent data contamination, yielding 10,494 training and 2,400 test images across 296 unique uploaders. Bengal-HP_RU exhibits substantial diversity in subject age, gender, occlusion, illumination, and background, reflecting realistic in-the-wild conditions. The dataset is publicly available at https://doi.org/10.17632/xbw9kr37jb.2.
