Overview

Meal intake procedure was captured in a controlled laboratory environment using 4 Sony XCD-V60CR digital video cameras positioned such as to capture the participants frontal, upper frontal, 45° and profile view. An instance of each camera viewing angle is shown in figure.All sequences were recorded at a resolution of 640×480 pixels, at a frame rate of 15 frames per second and were saved in avi format.In the recordings 12 persons (6 females and 6 males) participated with Caucasian origin aging between 22 and 39 years old with different facial characteristics (eye glasses, beard etc.). Each person participated in 4 distinct meal intakesessions and two videos for each one session were recorded: one depicting the participant wearing a blouse or a shirt with long sleeves and one wearing a t-shirt or a blouse with short sleeves. In total, 8 videos are available for each person for each session. This results in a database consisted of 384 video sequences.

Scenario

The meal intake scenario that each participant has performed involves eating with spoon, cutlery, fork, hands and drinking from cup, glass and straw performed in the following order:

• He/she enters the room, sits in front of the frontal camera and starts eating cereals with a spoon (4 iterations) and he/she drinks water from a cup (4 iterations).
• The bowl is replaced with a plate and the cup with a glass of water. The person continues eating using a knife and a fork (4 iterations) and drinks from a cup (1-2 iterations).
• He/she eats the same food using only the fork (the hand holding the fork is changed, 4 iterations). He/she drinks again (1-2 iterations).
• The person puts a straw in his/her glass of water and continues eating with his/her hand (4 iterations) and drinking from straw (4 iterations in total).
• The person, also, eats with his/her hands a loaf of bread, a croissant or a sandwich (4 bites).
• Finally, the person spends some time doing something else besides eating, like thinking/wondering, paying attention, talking, reading, writing, touching his/her hair, ear, glasses, chin or yawing.
• He/she stands up and exits the room.

Annotation

Along with the recorded videos, two annotation txt files are available for each session. The first txt file refers to the frontal view video and annotates the human performed movement per video frame during meal intake procedure. The movement types are described in the ‘annotation.doc’ file that accompanies the txt files.

The second txt file contains information for the synchronizarion of all video files with respect to the frontal view video file. The 4 numbers written in a column form define the difference in frames between a specific frame in the video captured by the frontal view camera and the videos captured by the other cameras in the following order: frontal camera, 45° camera, profile camera, upper frontal camera.
