Title: Image-based life-logging: what it’s about?

Abstract:

Recently appeared Life-logging technology consists in acquiring personal data by wearing an electronic sensor over long periods of time. Wearable computing is moving to the cusp of common-place consumer technology, being in the top of The Hype Cycle in the Gartner industry analysis. The benefit of image-based life-logging acquired by a wearable camera is that it gives rich information able to generate explanations and visualize the circumstances of the person’s activities, scene, state, environment and social context that definitely influence his/her way of life (contextual information). At the same time, several natural privacy and legal concerns appear for people wearing devices at all times that can record video and take pictures.

In this talk, I will present our research on Life-logging based on the use of wearable cameras for recording person’s lifestyle. One of the challenges of image-based Life-logging is how to extract meaningful semantic information from the huge amount of images (4000 images acquired per day or more than 100.000 images acquired per month). To this purpose, I will address several computer vision problems like: Video segmentation and analysis; Event detection; Social interaction, and Lifestyle characterization. We will discuss potential health applications of Life-logging like: Reinforcing memory of people with mild-cognitive impairment, and Healthy habits improvement by monitoring, analysis, and lifestyle characterization from life-logging images.
