In recent years, remarkable progress has been made towards large-scale content-aware image search. However, there is still a long way to go to bridge the two “gaps”: semantic gap and intent gap. Large-scale data brings us both challenges and opportunities to tackle these difficulties. In this talk, we will review existing image search and understanding schemes and then focus on large-scale content-aware image search. We will discuss the connections and differences among different large-scale CBIR techniques such as partition tree, clustering, hashing, graph and inverted index, and then introduce a few exemplary scalable approaches including graph based search, color map based search, and concept map based search. For each exemplary approach, we will discuss how to make it work for billions of images.

The limitations will then be analyzed for these techniques, followed by introducing indexing and searching schemes based on web-scale image content understanding. Connections between search and content understanding will be also discussed. And last we will talk about challenges and opportunities along this direction.
