ESR photo Research project "Behaviour modelling and life logging" About the project Lifelogging is a recent ICT technology that uses wearable sensors (e.g. cameras, trackers, wearable sensors) to capture, store, process and retrieve the different situations, states and context of an individual in daily life. Using a wearable camera that automatically takes 3 images per minute provides about 2000 pictures at the end of each day that can illustrate in detail which activities the person wearing the camera has done - e.g. how (s)he eats, what places (s)he visited, with whom (s)he interacted, what events (s)he attended, etc. In this way, the topic of this thesis is lifelogging in order to create personalized tools and services to monitor, store and process the behavioural skills, nutrition patterns, social environment, context and proper physical activities during long periods in an objective way. Start date: April 2021 Progress of the project Under this project, there was carried out state-of-the-art research on multiple topics related to egocentric vision and lifelogging from a computer vision perspective. This includes fields of segmentation that divides large streams of images into predefined subgroups, action recognition and activity recognition when from given data like a video or a stream of pictures algorithms are predicting what camera user does in the scene, methods for processing food-related scenes, state of automatic processing methods for social interaction tracking. Except for the research of techniques in various disciplines, a database of datasets has been created available in the field, which is helpful for this project and could be applied to different tasks of egocentric vision. This research has led to the creation of questions and definitions of open problems. This defines the following steps and fields for further study and improvement. These open problems are related to the automatic description of a diet focused on drinking activities with less interest given by the scientific community. Other fields are food diet estimation and hand-related actions monitoring, including medicament intake and description of social signals between people in social interactions and meetings that can be correlated with mental disorders. For further steps and experiments, pipelines for video understanding and action recognition were created, which were tested with existing methods for this task.
