The TUM Gait from Audio, Image and Depth (GAID) database
Recognizing people by the way they walk - also known as gait recognition - has been studied extensively in the recent past. Recent gait recognition methods solely focus on data extracted from an RGB video stream. With this work, we provide a means for multimodal gait recognition, by introducing the freely available TUM Gait from Audio, Image and Depth (GAID) database.
This database simultaneously contains RGB video, depth and audio. With 305 people in three variations, it is one of the largest to-date. To further investigate challenges of time variation, a subset of 32 people is recorded a second time.
A detailed description of the database can be found in . This reference also includes experiment definitions as well as baseline results.
In order to load a raw file from the database, you can use the following code in MATLAB:
>> fid = fopen('test.raw');
>> depth_image = fread(fid, [640,480], 'uint16')';
>> fclose (fid);
The database is made freely available for research purposes. To get an impression of the database, the data for the person with ID=1 can be downloaded without password.
The complete set of data is distributed via a password protected download. In order to obtain the password, the release agreement must be signed by a legal representative of your institute (e.g. the head of the institute). You can return the signed copy via mail, e-mail or fax. The database is split into several files, each containing a feature set, or modality for all 305 subjects. Currently, we provide
- RGB image sequences (jpg files, ~30 GB)
- Depth image sequences (16-bit raw files, ~16 GB)
- Four channel audio (16kHz wav files, ~1.6 GB)
- Tracked RGB image sequences (jpg files, ~3.6 GB)
- Tracked depth image sequences (16-bit raw files, ~0.3 GB)
We provide the tracked version of the RGB and depth image sequences for convenience. These are obtained by tracking the person and cropping both RGB and depth data around the tracked person.
In order to get access to the ftp server to download the data, please contact us and send us the signed release agreement. If you use this database in your research, please cite  in your paper.
