Robust Object Re-Identification in Large Repository for Mobile Visual Search


报告题目:Robust Object Re-Identification in Large Repository for Mobile Visual Search

报告人:Zhu Li教授





报告摘要:Mobile visual search has many important applications in surveillance, security, virtual and augmented reality and e-commerce. A central technical problem to enable these application is the visual object identification against a very large repository. Robust local features that are invariant to the image formation process, good aggregation and compression schemes for the local features that offers indexing efficiency and matching accuracy, are the focus of the recent MPEG standardization effort on Compact Descriptor for Visual Search (CDVS).  In this talk, I will review the key technical challenges to the CDVS pipeline, and covering the novel contributions made in the CDVS work on alternative interesting points detection, more efficient interesting points aggregation scheme, indexing / hashing issues for object re-identification against large repository, and retrieval system optimization, as well as the future directions of the research in this area with new depth sensors and video inputs.
