Annotation contextuelle automatique avec PhotoMap

ABSTRACT

We present a mobile and context-aware system, called PhotoMap that provides semi-automatic annotation about the spatial, temporal and social contexts of a photo. (i.e., where, when, who and what was nearby). The PhotoMap application captures the photo shot context when a user takes a picture with her camera phone. The mobile client gets the geographic position of the device, date and time information, bluetooth addresses of the nearby devices. PhotoMap explores these gathered metadata to infer high level contextual information such as, nearby user's friends, weather conditions, device address, and nearby important objects. PhotoMap uses these metadata for organizing, sharing and retrieving the photo files.
