Head Pose Image

The head pose database is a benchmark of 2790 monocular face images of 15 persons with variations of pan and tilt angles from -90 to +90 degrees. For every person, 2 series of 93 images (93 different poses) are available. The purpose of having 2 series per person is to be able to train and test algorithms on known and unknown faces (cf. sections 2 and 3). People in the database wear glasses or not and have various skin color. Background is willingly neutral and uncluttered in order to focus on face operations. All images have been taken using the FAME Platform of the PRIMA Team in INRIA Rhone-Alpes. To obtain different poses, we have put markers in the whole room. Each marker corresponds to a 2D pose (pan, tilt). Post-it are used as markers. The whole set of post-it covers a half-sphere in front of the person. ? In order to obtain the face centered on image, the person is asked to adjust the chair to see the device in front of him. The person stands at a distance of 2 meters from the camera. After this initialization phase, the person stares successively at 93 post-its, without moving his eyes. All images are obtained by using this method. ?

头部姿态基准数据集包含15名受试者的2790张单目人脸图像，所有图像的人脸偏航角与俯仰角均覆盖-90°至+90°的姿态变化范围。每名受试者对应两组图像采集序列，每组序列包含93张图像，对应93种不同的人脸姿态。设置每名受试者两组采集序列的目的，在于支持在已知人脸与未知人脸场景下开展算法的训练与测试（详见第2、3章节）。数据集中的受试者涵盖佩戴眼镜与不佩戴眼镜两类群体，且肤色分布多样。为突出人脸主体，特意将采集场景的背景设置为中性无杂物的纯色环境。所有图像均由法国国家信息与自动化研究所（INRIA）罗纳-阿尔卑斯分院PRIMA团队的FAME平台（FAME Platform）采集完成。为采集不同的人脸姿态，本研究团队在整个采集房间内布置了标记物，每个标记物对应一组二维姿态参数（偏航角、俯仰角），本次采集采用便利贴（Post-it）作为标记物。所有便利贴标记物覆盖受试者前方的半个球面区域。为确保人脸位于图像中心位置，受试者需调整座椅位置，使其能够直视前方的采集设备。受试者与相机的采集距离固定为2米。完成初始化步骤后，受试者需依次凝视93张便利贴标记物，且全程保持眼部不动。所有图像均通过上述采集流程获取。
