Objectively recognizing eating behaviour and associated intake

Automatic detection of intake gestures is a key element of automatic dietary monitoring. Several types of sensors, including inertial measurement units (IMU) and video cameras have been used for this purpose.

The common machine learning approaches make use of the labelled sensor data to automatically learn how to make detections.

One characteristic, especially for deep learning models, is the need for large datasets. To meet this need, we collected the Objectively Recognizing Eating Behaviour and Associated Intake (OREBA) dataset.

The OREBA dataset aims to provide a comprehensive multi-sensor recording of communal intake occasions for researchers interested in automatic detection of intake gestures and other behaviours associated with intake.

Two scenarios are included, with 100 participants for an individual dish and 102 participants for a shared dish. Available sensor data consists of synchronised frontal video and IMU with accelerometer and gyroscope for both hands.
