EVIP：用于非接触式眼压测量的基于眼视频的眼压数据集

现有的面部 rPPG 数据集（例如，用于心率或血氧饱和度监测）主要捕获全脸区域，重点关注来自前额、脸颊或眶周区域的皮肤灌注信号。这些数据集缺乏针对眼部结构（瞳孔、虹膜、巩膜）和直接眼压测量的专门注释，因为它们的核心目标是一般生理参数估计，而不是针对眼睛的压力分析。相比之下，EVIP 经过独特设计，可将眼部生理信号与眼压值联系起来：它提供高分辨率眼部视频和经过临床验证的眼压测量，从而能够从眼部区域提取与眼压相关的 BVP 特征。该文件夹包含两个子文件夹 EVIP-1 和 EVIP-2，分别表示 EVIP 数据集的两个版本。每个子文件夹都包含以 MP4 格式录制的眼部视频，以及包含记录和存储在 CSV 文件中的实际眼压值的数据文件。对于 EVIP-1 文件夹，有来自 30 名参与者的 60 个眼睛视频，按阿拉伯数字顺序命名，以及一个“EVIP-1.CSV“数据文件。该数据包括一个名为“实际值”的列，其中包含实际的眼压记录，该记录对应于视频文件从上到下的顺序。EVIP-2 以相同的方式存储，包含来自 60 名参与者的 122 个眼部视频，以及一个同步记录的实际 IOP 值数据文件，名为“EVIP-2”。CSV“。

Most existing facial rPPG datasets (e.g., for heart rate or blood oxygen saturation monitoring) primarily capture full-face regions, focusing on skin perfusion signals from the forehead, cheeks, or periorbital areas. These datasets lack specialized annotations for ocular structures (pupil, iris, sclera) and direct intraocular pressure (IOP) measurements, as their core objective is general physiological parameter estimation rather than ocular pressure analysis. In contrast, the EVIP dataset is uniquely designed to link ocular physiological signals with intraocular pressure values: it provides high-resolution ocular videos and clinically validated IOP measurements, enabling the extraction of IOP-related BVP features from the ocular region. This folder contains two subfolders, EVIP-1 and EVIP-2, corresponding to the two versions of the EVIP dataset. Each subfolder contains ocular videos recorded in MP4 format, alongside data files that store the actual intraocular pressure values recorded and saved in CSV format. For the EVIP-1 subfolder, there are 60 eye videos from 30 participants, named in sequential Arabic numerical order, along with a data file named "EVIP-1.CSV". This data file includes a column titled "Actual Values" that contains the actual IOP records, which correspond to the top-to-bottom order of the video files. The EVIP-2 subfolder is stored in the same manner, containing 122 eye videos from 60 participants, along with a data file named "EVIP-2.CSV" that stores synchronously recorded actual IOP values.
