Compact descriptors for mobile visual search and MPEG CDVS standardization

Abstract

In this paper, we present the state-of-the-art compact descriptors for mobile visual search. In particular, we introduce our MPEG contributions in global descriptor aggregation and local descriptor compression, which have been adopted by the ongoing MPEG standardization of compact descriptor for visual search (CDVS). Standardization progress will be introduced. Other issues including visual object databases and MPEG CDVS impact on visual search industry will be discussed as well.
