Computational light transport using space, time, and polarization
… measured by millions of pixels. The framework of computational light transport was introduced to model this complex interaction between light and matter in a tractable space. In this thesis, we study new methods to invoke space, time, and polarization into a computational light transport …

Physically based geometry and reflectance recovery from images
… lattice. Secondly, we study the problem of computational relighting using RGB-D data, where the depth data is acquired through a Kinect sensor and is often noisy. We show how the inclusion of noisy depth input helps to resolve ambiguities in the recovery of shape and reflectance in the …

A unified framework for identifiability analysis in bilinear inverse problems
… applications, including inverse rendering in computational relighting (albedo estimation with unknown lighting), blind phase and gain calibration in sensor array processing, and multichannel blind deconvolution (MBD). Applying our unified framework to BGPC, we derive sufficient conditions for …

Signal representations: from images to irregular-domain signals
Efficient representations of high-dimensional data such as images, that can essentially describe the data with a few parameters, play a vital role in many problems in signal processing and related fields, ranging from signal compression and denoising to inverse problems. This thesis studies the …
