Mitch Parry (2007), Separation and Analysis of Multichannel Signals PhD Thesis [PDF], Georgia Institute of Techniology, College of Computing, Atlanta, GA. (Advisor: Irfan Essa) Abstract This thesis examines a large and growing class of digital signals that capture the combined effect of multiple underlying factors. In order to better understand these signals, we would like […]
Vivek Kwatra (2005), “Example-based Rendering of Textural Phenomena”PhD Thesis, Georgia Institute of Technology, College of Computing (Advisors: Aaron Bobick, Irfan Essa) [URI], 19-Jul-2005 Abstract This thesis explores synthesis by example as a paradigm for rendering real-world phenomena. In particular, phenomena that can be visually described as texture are considered. We exploit, for synthesis, the self-repeating […]
Drew Steedly (2004)“Rigid Partitioning Techniques for Efficiently Generating 3D Reconstructions from Images”PhD Thesis, Georgia Institute of Technology, College of Computing. (Advisor: Irfan Essa) [PDF] [URI] Abstract This thesis explores efficient techniques for generating 3D reconstructions from imagery. Non-linear optimization is one of the core techniques used when computing a reconstruction and is a computational bottleneck […]
We define a Spine as a branching axial structure representing the shape and topology of a 3D objects limbs, and capturing the limbs correspondence and motion over time. … In general, our approach combines the objectives of generalized cylinders, 3D scanning, and markerless motion capture to generate baseline models from real puppets, animals, and human subjects.
Antonio Haro (2003) “Example based processing for image and video synthesis” PhD Thesis, Georgia Institute of Technology, College of Computing, Atlanta, GA, [URI] [PDF] (Advisor: Irfan Essa) Abstract: The example based processing problem can be expressed as: “Given an example of an image or video before and after processing, apply a similar processing to a […]
Irfan Essa (1994), “Analysis, interpretation and synthesis of facial expressions“, PhD Thesis, MIT, Cambridge, MA, USA. (Advisor: Alex (Sandy) Pentland) [PDF] Abstract This thesis describes a computer vision system for observing the “action units” of a face using video sequences as input. The visual observation (sensing) is achieved by using an optimal estimation optical flow […]
