TVHeads (Top-View Heads) Dataset

The TVHeads (Top-View Heads) dataset contains depth images of people from top-view configuration. In particular, the purpose of this dataset is to locate the heads of people who are present below the camera. It contains a total of 1815 depth images (16 bit) with a dimension of 320x240 pixels. Furthermore, after an image preprocessing phase, the depth images are also converted, with an appropriate scaling, in order to obtain an images (8 bit) where the heads silhouette is highlighted by improving image contrast and brightness. The ground truth was manually labelled by 6 human annotators.TVHeads（顶视头部，Top-View Heads）数据集包含顶视视角下的人体深度图像。本数据集的核心目标为定位相机视野下方的人体头部。该数据集总计包含1815张16位深度图像，分辨率为320×240像素。此外，在完成图像预处理流程后，还会通过适当的缩放操作对深度图像进行转换，以生成8位图像，通过优化图像对比度与亮度来突出头部轮廓。该数据集的基准真值标注由6名人工标注员手动完成。
