Abstract
Computational imaging and display principles are “enabling technologies” with the potential to drive transformational changes across multiple future application scenarios: Novel breeds of cameras could see through deep tissue, fog, or smoke. Precise and fast 3D scanners could enhance medical diagnosis and therapy, and become essential for measuring dynamic scenes during robotic surgery, autonomous navigation, or additive manufacturing. Novel 3D display and eye-tracking methods could enable the next wave in AR/VR. Amidst these seemingly endless possibilities, the knowledge about fundamental physical and information-theoretical limits in computational imaging proves to be a powerful tool: Limits often manifest as uncertainty products, allowing us to optimize specific system parameters (e.g., speed) by trading off less critical information for a given application. Moreover, recognizing that our imaging system already operates at the physical limit (e.g., of resolution) can help avoid unnecessary effort and investment. In this talk, Florian Willomitzer will highlight the virtue of limits in computational imaging by discussing recent research directions of his group: Among other topics, he will introduce a set of techniques that use so-called “synthetic waves” for computational holographic imaging through scattering media, and allow the capture of “light-in-flight” information without the need for pulsed lasers or fast detectors. Furthermore, he will present novel principles for 3D imaging on challenging shiny and specular surfaces, enabling, for example, fundamentally new techniques for accurate and fast eye tracking.
