老人室内活动分析项目

 

Senior home monitoring

   The current video database containing twelve types of human actions (drinking, eating meals, eating snacks, getting out of bed, going to bed, sleeping, smoking, walking, playing mahjong, washing face, washing feet and watching TV) performed by 6 seniors in their own rooms. We have collected this dataset of 4 month long (the location is not disclosed here to avoid exposing the identities of the authors). Daily activities in senior homes were recorded by using one SONY DCR-SR68E camera per room. The recording lasts for 10 days for each senior. The total size of the record data is approximately 1.8TB with 25f/s. Some example images from the recorded video dataset are illustrated below. All samples were downsampled and compressed (Xvid MPEG-4 Codec )to the spatial resolution of 360x288 pixels.

Data labeling is extremely labor intensive. It is still ongoing.

Sample sequences for each action:

 

老人室内活动分析

目前的视频数据一共包括6位老人的12种常见室内活动(喝水、吃饭、吃零食、下床、上床、睡觉、抽烟、走路、打麻将、洗脸、洗脚、看电视)。我们通过在每个房间内安置一台SONY DCR-SR68E摄像机,前后共进行了为期4个月的拍摄(5月——8月),平均对每位老人拍摄了10天。一共拍摄了将近1.8TB的视频数据(25帧/秒)。下图是一些视频数据的截图。在实验中我们将原视频处理成分辨率为360x288的视频段。

由于数据标记的工作量很大,目前仍在进行中。
