Project Description

Computational cameras are imaging systems that are combinations of optics, electronics, and algorithms that jointly enable new approaches to image sensing. Computational imaging systems are of interest for applications such as polarization imaging, hyperspectral cameras, time-of-flight and depth imaging, light fields, high speed cameras, or cameras with small and exotic form factors. The internship will be to learn about computational imaging approaches, and work in an interdisciplinary team to develop new camera systems in one of the application domains.​

Research Interests

Professor Heidrich's core research interests are in computational photography and display, an emerging research area within visual computing, which combines methods from computer graphics, machine vision, imaging, inverse methods, optics and perception to develop new sensing and display technologies. Computational photography aims to develop new cameras and imaging modalities that optically encode information about the real world in such a way that it can be captured by image sensors. The resulting images represent detailed information such as scene geometry, motion of solids and liquids, multi-spectral information, or high contrast (high dynamic range), which can then be computationally decoded using inverse methods, machine learning, and numerical optimization. Computational displays use a similar approach, but in reverse. Here, the goal is to computationally encode a target image that is then optically decoded by the display hardware for presentation to a human observer. Computational displays are capable of generating glasses-free 3D displays, high dynamic range imagery, or images and videos with spatial and/or temporal super-resolution.

Desired Project Deliverables

​Depending on the background of the student, the work can be more optics oriented or more software oriented. Close collaboration with other team members is expected. Possibility for co-authoring a scientific article in a conference or journal.​
