讲座内容: Image collections are a tremendous source of information. Yet due to the semantic gap it is difficult to get access to their content and properly employ their context such as tags, geolocation, and other metadata. To move forward, we propose multimedia analytics solutions. These methods bring human experts and machine algorithms together in a synergetic manner where the machine does the bulk processing and the expert deals with the difficult decisions. Advanced interactive visualizations provide the means to let the expert understand the results of automatic processing and interactively provide the system with further guidance. Our solutions build upon our state-of-the-art visual concept detectors. From there we consider methods for interactively summarizing and exploring the collection. In particular we propose multimedia pivot tables, an extension of the pivot table reports found in spreadsheets and show how they provide highly flexible and versatile explorative capabilities. They provide a step towards methods to get valuable insight in large image collections.
