Light transport and optical phenomena

Whether in the synthesis or the analysis (interpretation) of images, we have to use strongly simplifying models for the physical nature of light and its interaction with the real world. My work deals with the development of light transport models that are closer to physics but still tractable in terms of storage and computational effort. By using simple but powerful extensions on top of established approaches, we have introduced techniques that achieved results of unprecedented quality in applications as diverse as 3D scanning, photorealistic rendering (offline and real-time), and display technology. Many unsolved problems will benefit from improved models of light transport.

Forward and backward graphics

My research is dedicated to the development of novel solutions to challenges in computer vision and image processing. In recent research projects, we have demonstrated the potential of analysis-by-synthesis techniques for problems such as the tomographic reconstruction of fluid mixing processes. This emerging family of methods marries a synthesis step (forward model of image formation) to an optimization loop, in order to solve the inverse problem of recovering the model parameters that best explain the given set of measured data. The forward step can be as complex as a full global illumination renderer! The resulting objective functions are often mathematically ill-behaved and therefore require careful selection and adaptation of suitable optimization schemes.

Computational sensing

The advent of digital image sensors, together with today's numerical methods and advanced compute hardware, allows us to revisit the history of engineering. A recurring theme in my work is to question established design principles that date back to the pre-computer age. For instance, we recently demonstrated a computational camera that, instead of a complex lens with up to several dozen individual glass elements, uses much simpler optics while still maintaining excellent picture quality. Thanks to current developments, in particular sparse codings, many other applications will benefit as we begin to treat computation as an integral component of the measurement process.

Graph. (Proc. SIGGRAPH Asia)}, volume = {34}, number = {6}, year = {2015}, month = nov, abstract = {Transient images help to analyze light transport in scenes. Besides two spatial dimensions, they are resolved in time of flight. Cost-efficient approaches for their capture use amplitude modulated continuous wave lidar systems but typically take more than a minute of capture time. We propose new techniques for measurement and reconstruction of transient images, which drastically reduce this capture time. To this end, we pose the problem of reconstruction as a trigonometric moment problem. A vast body of mathematical literature provides powerful solutions to such problems. In particular, the maximum entropy spectral estimate and the Pisarenko estimate provide two closed-form solutions for reconstruction using continuous densities or sparse distributions, respectively. Both methods can separate m distinct returns using measurements at m modulation frequencies. For m=3 our experiments with measured data confirm this. Our GPU-accelerated implementation can reconstruct more than 100000 frames of a transient image per second. Additionally, we propose modifications of the capture routine to achieve the required sinusoidal modulation without increasing the capture time. This allows us to capture up to 18.6 transient images per second, leading to transient video. An important byproduct is a method for removal of multipath interference in range imaging.}, doi = {10.1145/2816795.2818103} }

In this article, we search for imaging situations similar to uncalibrated integral optics, noticing that they are common in everyday life. We investigate light field capturing scenarios which are provided by commonly available items like cutlery as optical building blocks. Using a generic calibration approach based on structured light, we reconstruct the light path providing an unorthodox light field capturing setup. As the resulting data is unstructured and poorly sampled and thus unsuited for standard image-based rendering pipelines, we propose techniques for the processing of such light fields. Additionally, we have implemented a novel depth estimation scheme to guide the rendering process. We demonstrate the potential of these techniques on different scenes, both static and dynamic, recorded by combining a DSLR camera with household items.}, isbn = {978-3-905674-95-8}, doi = {10.2312/vmv.20151271} }

Press echo

Our project on looking around corners with time-of-flight sensors received significant attention in regional, national and international media: General Anzeiger Bonn (German), Kurzweil AI, optics.org, OSA Newsroom, gizmag.com, Daily Mail (UK), engineering.com.
Our simple-lens imaging project was featured on a variety of online and print news outlets: Gizmodo, Reddit, Technology Review Germany, Vision Systems. The technology is being commercialized by the start-up company Algolux, a fact that also received attention by the local news media: Vancouver Sun, Der Westen (German).
