ABOUT THE TALK

Recent computer vision approaches assisted by Deep Learning (DL) techniques have shown unexpected advancements in solving problems that did not seem obvious to automatize – such as face recognition, lip reading, plate recognition, or lung cancer diagnosis. However, there has been limited efforts from Computer Vision community to tackle food image recognition.

Food image recognition is a big challenge for DL from many points of view: just consider how many dishes exist around the world; or how many names a dish can have! Do we have DL techniques to overcome this?

In this talk, we review the field of food image analysis within a new framework: uncertainty-aware multi-task food recognition. After discussing our methodology to advance in this direction, we comment potential research, as well as its social and economic impact. We explain that the DL and Computer Vision community can bring powerful tools for professionals and individuals to get aware not only of what people eat but also of how people eat; which undoubtedly will be a step forward towards better health and well-being.
