Multimedia Processing Essentials

Abstract

As multimedia applications have become part of our life, preservation and long-term access to the multimedia elements that are continuously produced is a major consideration, both for many organizations that generate or collect and need to maintain digital content, and for individuals. In this chapter, we focus primarily on the following multimedia analysis and organization techniques that provide the basis for multimedia preservation: (a) photo/video annotation, which refers to the problem of assigning one or more semantic concepts to photos or video fragments, (b) photo/video quality assessment, which refers to the automatic prediction of a photo’s or video’s aesthetic value, (c) near-duplicate detection, which aims to identify groups of very similar items in large media collections, and (d) event-based photo clustering and summarization, which concern the selection of the most characteristic photos of a photo collection so as to create a storyline that conveys the gist of this collection.
