Inverse rendering techniques for physically grounded image editing
… properties from single images. The goal of these inverse rendering techniques is to estimate the configurations of scene elements (geometry, materials, luminaires, camera parameters, etc) using only information visible in an image. Such algorithms have applications in robotics and computer …

Structure from duplicates: Neural inverse rendering from a single image
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2026-05-01

Shape, Reflectance, and Illumination From Appearance
… passively from the object’s appearance. Such “inverse rendering” capabilities enable 3D understanding of our world (as desired in autonomous driving, robotics, etc.) and computer graphics applications such as relighting, view synthesis, and object capture (as desired in extended reality [XR], …

Differentiable volume rendering using signed distance functions
… graphics and computer vision context to solve inverse rendering problems. These methods can be used to infer camera parameters, material properties, and even object pose and geometry from 2D images. One of the challenges that faces differentiable rendering systems is handling visibility terms …

Inverse Inverse Graphics
… if we think of the audience's mind as solving inverse problems—perception as inverse rendering, action understanding as inverse planning—then we can think of expression as solving a kind of *inverse* inverse problem. I then show how to implement such "inverse inverse" methods computationally. …

Algorithms & Systems for Differentiable Graphics Programming
… a centerpiece for learning-based approaches in inverse rendering, novel-view synthesis, data & compute efficient rendering, and even 3D generative models. We see great advances in performance & fidelity when mixing classical wisdom from existing primitives like meshes and textures, and novel …

Physically based geometry and reflectance recovery from images
… can be cast as a set of physically based inverse problems. This thesis investigates three inverse problems on the recovery of scene properties and discusses how we can develop appropriate physical constraints and build them into effective algorithms. Firstly, we study the problem of …

Computational Discovery of Hidden Cues in Photographs
… Furthermore, we show that physically-based "inverse rendering" can be used to estimate how light travels within a scene, turning objects, like coffee cups or picture frames, into "object cameras". Physical models are quite fragile to small errors in estimated scene parameters. As such, we …

A unified framework for identifiability analysis in bilinear inverse problems
Bilinear inverse problems (BIPs), the resolution of two vectors given their image under a bilinear mapping, arise in many applications. Without further constraints, BIPs are usually ill-posed. In practice, properties of natural signals are exploited to solve BIPs. For example, subspace constraints …

Signal representations: from images to irregular-domain signals
… ranging from signal compression and denoising to inverse problems. This thesis studies the design and applications of various representation systems for several classes of signals including images and signals on general graphs. The first half of the thesis deals with two different classes of …

Bilinear inverse problems with sparsity: Optimal identifiability conditions and efficient recovery
Bilinear inverse problems (BIPs), the resolution of two vectors given their image under a bilinear mapping, arise in many applications. Without further constraints, BIPs are usually ill-posed. In practice, parsimonious structures of natural signals (e.g., subspace or sparsity) are exploited. …
