Dem@Care – GAADRD Dataset


Dem@Care Project – GAADRD Dataset

Dem@Care is providing a public dataset, which is collected during lab experiments. The data collection took place in the Greek Alzheimer’s Association for Dementia and Related Disorders (GAADRD) in Thessaloniki, Greece. The datasets include video and audio recordings as well as data from physiological sensors. The dataset is available to the research community under specific terms of use.

General Info:

– The people recruited for this dataset were 25 elderly people, aged 65 and above, of both genders.

– The participant pool included people that were healthy and people suffering from conditions ranging from Mild Cognitive Impairment (MCI) to mild dementia, and in a few cases full-blown Alzheimer’s Disease (AD).

– The participants are asked to perform following activities of daily living (ADL):

Activities of Interest:

– Reading Article

– Watering Plant

– Preparing Drug Box

– Preparing Drink

– Turning On Radio

– Talking On Phone

– Balancing Account


Video Data:

– RGB and Depth images

– 640×480 resolution

– 25 videos

Ground Truth:

– Activities are manually annotated for each video.

The dataset can be downloaded by following the instruction in Dem@Care Dataset Web-Page.

Tracking Data:

– Videos have been processed for people detection and tracking using [1] and [2].

– Tracking data for 25 videos can be downloaded from here: Tracking_Data_GAADRD

– Tracking data contains following information in XML-format:
