Abstract

With the rapid development of the Internet and multimedia technologies over the last decade, a huge amount of data has become available, from text corpus, to collections of online images and videos. Cheap storage cost and modern database technologies have made it possible to accumulate large-scale datasets. However, the ever-growing sizes of the datasets make it harder to search useful information from such data. A fundamental computational primitive for dealing with massive multimedia datasets is the similarity search problem. Multimedia similarity search aims to preprocess a database so that given a query object, one can quickly find its similar objects in the database. Searching similar objects from a large dataset in high-dimensional spaces is at the heart of many multimedia applications, such as near-duplicate retrieval, multimedia tagging, recommendation, and so on. Driven by its significance, lots of efforts have been made on this topic. The goal of my research is to design efficient hashing methods for large-scale multimedia search. In this paper, we first present the general framework for multimedia similarity search and discuss the latest improvements and progresses in the field. Then we describe the contributions we have made to effectively and efficiently search similar multimedia objects from large-scale databases. Finally, we discuss the future work and draw a conclusion.
