EURECOM Kinect Face Dataset
Depth information has been proved to be very effective in Image Processing community and with the popularity of Kinect since its introduction, RGB-D has been explored extensively for various applications. Therefore, the need for the development of Kinect image & video database is crucial.
Here, our effort is to create a Kinect Face database of images of different facial expressions in different lighting and occlusion conditions to serve various research purposes.
The Dataset consists of the multimodal facial images of 52 people (14 females, 38 males) obtained by Kinect. The data is captured in two sessions happened at different time period (about half month). In each session, the dataset provides the facial images of each person in 9 states of different facial expressions, different lighting and occlusion conditions: neutral, smile, open mouth, left profile, right profile, occlusion eyes, occlusion mouth, occlusion paper and light on [Figure 1]. All the images are provided in three sources of information: the RGB color image, the depth map (provided in two forms of the bitmap depth image and the text file containing the original depth levels sensed by Kinect) as well as 3D. In addition, the dataset comes with the manual landmarks of 6 positions in the face: left eye, right eye, the tip of nose, left side of mouth, right side of mouth and the chin [Figure 2]. Other information of the person such as gender, year of birth, glasses (this person wears the glasses or not), capture time of each session are also available.
Figure 1: Illustration of different facial variations acquired in our database: (a) neutral face; (b) smiling; (c) mouth open; (d) strong illumination; (e) occlusion by sunglasses; (f) occlusion by hand; (g) occlusion by paper; (h) right profile face and (i) left profile face. (Upper: the RGB images. Lower: the depth maps aligned with above RGB images.).

The recording took place in an indoor environment in the Lab at EURECOM Institute. Each person is recorded twice in two sessions happening at different time. In each session, the person is asked to perform different face states in front of the Kinect camera at a distance of around 1 meter. Images are then normalized by cropping at the size of 256x256 centered by the face, with the upper left corner at the coordinates of (192,74) [figure 3]

The structure of the database is illustrated in the following hierarchy [figure 4]:

Where, the meaning of subpart is as follows:
0001: Folder name with person identifier 0001, each person is determined by an identifier of 4 digits.
