Portrait of Lei Zhang

Lei Zhang

Senior Researcher


Lei Zhang is a senior researcher in Microsoft Research, working with the Cloud Computing and Storage group on visual recognition and exploring the solutions that can leverage the power of cloud computing.

Prior to this, he worked with Microsoft Research Asia for 12 years as a senior researcher, leading a research team working on visual recognition, image analysis, and large-scale data mining. His years of work on large-scale, search-based image annotation has generated many practical impacts in multimedia search, including a highly scalable solution of duplicate image clustering for billions of images. From 2013 to 2015, he moved to Bing Multimedia Search as a principal development manager, helping develop cutting-edge solutions for web-scale image analysis and recognition problems, including image caption generation and high precision image entity linking.

Lei is a senior IEEE member and a senior ACM member, and has served as editorial board members for Multimedia System Journal, as program co-chairs, area chairs, or committee members for many top conferences. He is the author or co-author of 100+ published papers in fields such as multimedia, computer vision, web search and information retrieval, and holds 40+ U.S. patents for his innovation in these fields.

Lei earned all his degrees (B.E., M.E., and Ph.D) in Computer Science from Tsinghua University, and currently also holds an adjunct professor position in Tianjin University.

MSRA-CFW: Data Set of Celebrity Faces on the Web

Dataset Descriptions The dataset includes image URLs for 202792 faces. The labels of the faces are automatically generated by the algorithm in [1], with high accuracy. To facilitate downloading the images, we provide a number of URLs for the near-duplicates…

MindFinder: Finding Images by Sketching

Established: August 12, 2010

Sketch-based image search is a well-known and difficult problem, in which little progress has been made in the past decade in developing a large-scale and practical sketch-based search engine. We have revisited this problem and developed a scalable solution to…

Website Structure Understanding and its Applications

Established: August 12, 2010

Website structure understanding can be treated as a reverse engineering for the purpose of automatically discovering the layout templates and URL patterns of a website, and understanding how these templates and patterns are integrated to organize the website. The study…
