NICU-Care Dataset

The NICU nursing dataset has a hierarchical file structure. At the top level, directories are named after action categories (e.g., the Change Diaper/ folder contains all instances of the diaper change action). Within each action folder, the data is further separated by camera view, usually subfolders like Top/ and Right/, since each clinical program is shot from two different angles. This structure (Action → View) allows for easy access to all videos for a particular action, with the option to focus on a specific viewpoint if needed. The name of each video file contains a wealth of information about the recording. We have adopted a uniform naming convention: ActionCode_View_NurseID_Instance.mp4. For example, a file named CD_Rview_A_1.mp4 can be interpreted as follows: CD denotes the “change diaper” action, the Rview indicates capture from the right camera view, A is the anonymous identifier of the nurse (caregiver) performing the operation, and 1 indicates that this is the first recorded instance of a diaper change operation performed by nurse A. The following is an example of a diaper change operation. Similarly, the top view recording of the second diaper change by the same nurse might be labeled CD_Tview_A_2.mp4, and a different action code would be used for the feeding action (FB for bottle feeding). By embedding category, viewpoint, subject, and session information in the file names, we ensure that each file is self-descriptive and unique. This naming scheme and folder organization greatly facilitates data retrieval. One can query files by action type or viewpoint at a glance, while also laying the groundwork for program access.
