Um ambiente para anotação de localização e eventos em coleções de fotografias.

Abstract

Due to the large number of pictures that is currently generated, it is very important to have techniques to organize, search and retrieve such images. Organize a collection of photos with thousands of images is not a simple job, and to associate data from social networks with the photographs is even more laborious. Personal photographs are commonly organized by reference to the following questions: "Who? Where? When?". Considering the three important questions, this work focuses efforts on the questions "Where?" and "When?". With these two questions in mind, the focus will be on location ("Where?") and events ("Where?" and "When?"). The overall objective is to offer an environment for annotating location and social events. This annotation is aided by the techniques proposed in this work. The experiments with location propagation techniques indicate that the choice of the propagation technique should happen considering the behavior of each user. Therefore, in addition to propagation techniques, is proposed, in this work, an automatic selection of location propagation techniques. The experiments performed to validate the social event detection technique presented good results and, in addition to performing event detection, can also be used to group photographs belonging to the same event. Finally, this work presents a tool to unite the annotation location with the annotation of events.
