Short Talk 1 - Supporting Media Bricoleurs with Cemint

Scott Carter

When expository video is made interactive it can be useful above and beyond non-interactive video because it can be repeated, accessed randomly, and annotated. FXPAL and many other labs have in the past explored a variety of such interactive video tools. But we would like to go a step further than interaction to facilitate what Lévi-Strauss described as a “dialogue with the materials”. By applying to video the same techniques and metaphors we apply to other media such as cut-and-paste, drag-and-drop, and spatial editing, we can support the construction of a new type of multimedia document in which spatial and temporal layouts have equal weight, can influence one another, and through which content can flow in any direction. 

In our lab we are beginning to develop a suite of tools to support such seamless inter-media synthesis in multimedia documents. The suite, called Cemint (for Component Extraction from Media for Interaction, Navigation, and Transformation), includes mobile- and web-based tools that allow users to create temporal content from spatial resources and vice versa. In this talk I  will discuss some tools we have built within this framework as well as opportunities for future work.

Short Talk 2 - Introduction to Large Scale Nearest Neighbor Search Problems and Methods

Junfeng He

We are witnessing a big data era, in which billions or more data with high dimensions can easily be found on the Web multimedia, social networks, enterprise data centers, surveillance sensor systems, etc. Nearest neighbor (NN) search is fundamental to many applications dealing with those large scale data sets,  including content based retrieval, ranking, recommendation, graph/social network research, as well as other machine learning problems.

This talk will give a brief introduction/overview about large scale nearest neighbor search problem and methods, and show some applications and demos on visual search engine.
