Projects

3D Object Reconstruction and Recognition

Established: May 1, 2015

We study the problem of 3D object reconstruction and recognition. For reconstruction, we aim at developing algorithms and systems to lower down the barrier of 3D reconstruction for common users. In this way, we can collect a world-class 3D object…

Picto: A large scale visual indexing and recognition system

Established: September 1, 2009

Object image recognition is a challenge but important problem. Towards addressing this problem, we initialed the Picto project. Our research in this project covers three fundamental aspects of this problem: low-level image features, middle level image representations, and indexing and…

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…
