PhotoGeo - uma biblioteca digital de fotografias com suporte de geoprocessamento.

Abstract

Since digital cameras made photography capturing easy, people are producing and storing an enormous amount of digital images. This caused an increased complexity in managing this kind of media file. Furthermore, the mobile devices with embedded GPS and digital cameras are capable of store temporal (timestamp of the shot) and geographic (latitude and longitude) information in image files metadata, enabling the treatment of the geographical aspects of photography. The existing geographic photo organizers, however, do not efficiently explore spatial-temporal metadata. In this study, we propose a new photo organizer tool - PhotoGeo - which provides the functionalities of organizing, navigating, annotating, and searching geo-referenced photos, which has enhanced usability and adequately explores geographic and temporal information. PhotoGeo proposes a novel automatic photo organizing mechanism which classifies pictures based on metadata and external sources. It also proposes a multi-modal interface to enable navigation within a photo collection, accompanied by a mechanism to perform advanced search in photography collections which explores the conventional, spatial, and temporal domains. Another very important contribution of PhotoGeo, is a new solution to suggest identification of people who are subject in the photos, expanding and utilizing the contextual informations of user.
