Face Video Data

We recorded four different sessions. The ﬁrst session consists of a resting scenario where no head or facial motion is performed and the illumination is more or less static. In the second session the users are asked to perform head as well as facial motions but the illumination remains static. The third session is performed during an exercise on a bicycle ergometer in a gym where no further instructions are given to the user. The fourth sessions is recorded during an urban conversation including head and facial motions as well as natural varying illumination conditions. The images above show some example images taken from the recordings during the different sessions. Every session is recorded over an one minute time span, except the ergometer session which is recorded over a 5 minute period. In total 25 users were ask to participate resulting in an amount of 100 video recordings with approximately 200 min total duration; more than three hours. The data collection consists of 20 male and 5 female in the range of 25-42 years. The majority ethnicity is Caucasian. The camera device is selected as Logitech HD C270 webcam and as reference ground truth measurements we synchronized a common ﬁnger pulseoximeter, a CMS50E PPG device, over its serial port communication protocol. The average frame rate of the camera is set to 25 FPS and for the pulseoximeter 60 FS. The camera video stream is captured uncompressed with auto-exposure and stored into an AVI container. For every captured image the time stamp is stored too. The pulseoximeter signal is stored together with the device’s pre-computed heart rate information.

Downloads

NOTE:
Due to ongoing bandwidth hustle,
there are no sessions for dowload available currently.
It seems the company isn't willing to provide storage and
bandwidth for hosting the LGI videos anymore.
I'm sorry that such relatively simple and sensible things are torpedoed by various parties.

Since I've rescued the first six sessions I might be able to provide these for the community
in case someone has enough cloud storage where I could upload the zip archives.
In the mean time i'm going to setup a small server at home for hosting the sessions.

Or try to contact the company CanControls in Aachen/Germany.

Ground Truth for BVP

Hi,

Thanks for sharing this dataset publicly. I have a question for this dataset. Does this dataset consist of ground truth BVP?

Best,
Li-Yun

Dataset

Hello,
Is there any chance that you can provide the part of dataset that is missing, from 7 to 25?
Thanks 😉

How to synchronize the video and ppg signal

How do the video and ppg signal synchronize, they are different devices

question anbout the sensor's xml data

thank for your ppg data and videos, it is very helpful. Is the heart value of the xml document in the ..hr value... fileld?

xml file

Hello, each video corresponds to two XML files, how to use XML?
In addition, video sampling frequency and finger pulse sampling frequency are inconsistent, how to synchronize?

Downloads either crash or give corrupted zip files

Hi all,

Unfortunately, all our attempts to download dataset archives failed. Each download was either crashed, or the result is not a valid zip archive. Sometimes the archive is almost valid -- 7zip allows to extract almost all files from it (but not all of them).

It seems that there is an error on the server side:
when we compared first 10,000,000 bytes of two versions of one archive, received from two different attempts to download, we found out that from some place two pieces of archive were swapped (size of each piece was about 3000 bytes, but it was sufficient to break the zip format).

We used to download on Linux curl, wget, aria2, Firefox, and Google Chrome.
We used to extract archives 7zip (several versions) and Linux unzip utility.

Could you say how could we download the archives?

How does one download this dataset?

A bit confused by the state of this repo as it seems a significant portion of this dataset isn't available for downloads, and the links provided seem to redirect to a totally unrelated website at the moment. I'm very interested in this dataset due to the third and fourth tasks described. Where do I need to go to download it?

<value612>
	<value0>612</value0>
	<value1>96</value1>
	<value2>66</value2>
</value612>

I guess that value1-value2 means the gound truth of Heart Rate. Am I right?

Download dataset

Hello,

The download links for the dataset do not seem to work.
They only show the website for CanControls, and the website seems to be obsolete.
Is there another way to download the data ?

Thank you very much,

Download link problem

Download links directs a website named cancontrols. I can't download the dataset.
