Research |
3D geometry (e.g., point clouds, triangle soups, meshes) is now easy to acquire (e.g., using Microsoft Kinect), model (e.g., using Blender), or simply download from model repositories (e.g, Turbosquid).
Such low-level data, however, makes subsequent handling and processing difficult, and hinders efficient use of model collections. Hence, I focus on
developing computational frameworks to extract high-level geometric abstractions from unorganized and heterogeneous 3D data. Specifically, I concentrate on the following themes:
(i) Shape Understanding: Algorithmically understand important relations between objects and object
parts in 3D objects, e.g., identify
symmetries, detect regular structures, create shape abstractions, or understand invariants and variabilties across model collections.
(ii) Smart Manipulation: Abstract input geometry into structure and variations to explicitly encode non-local constraints. Beyond immediate application to denoising and smart reconstruction, such abstractions
immediately allows intuitive and powerful shape manipulation, image-based editing, and constrained shape space exploration.
(iii) Computational Design: The ability to characterize design spaces using collection of (non-linear) constraints opens the possibility to directly optimize on design manifolds
leading to fabrication-aware design, guided shape exploration, and in general computational design.

Background |
Dr. Mitra is a Reader in Geometric Modeling and Computer Graphics in the Department of Computer Science, University College London (UCL). He was a Senior Lecturer at UCL from 2011-2012. Earlier, Dr. Mitra cofounded the Geometric Modeling and Scientific Visualization
( GMSV) center at KAUST and
was an Assistant Professor at Indian Institute of Technology (IIT) Delhi.
Before that Dr. Mitra was a postdoctoral scholar with Prof. Helmut Pottmann at
Technical University Vienna and
received his
MS (2002) and PhD (Sept. 2006) in Electrical Engineering from Stanford
University under the guidance of Prof. Leonidas Guibas and Prof. Marc Levoy (associate advisor).
He received his BS (advisor Prof. Prabir Biswas) from
Indian Institute of Technology (IIT) Kharagpur.
Dr. Mitra's research primarily centers around algorithmic issues in shape
understanding and geometry processing. He is equally interested in
applying analysis findings
(e.g., relations, constraints) to enable simple, smart, and captivating interaction possibilities, shape design, and design space exploration in general.
Dr. Mitra serves on the editorial board of Transactions on Graphics
(TOG), Computer Graphics Forum (CGF), Visual Computer, and Computer &
Graphics. He was the program cochair for
Symposium on Geometry Processing (SGP) 2012 and Shape Modeling International (SMI) 2011.
