This project will develop and analyze new algorithms for computational imaging, exploiting image structure to develop new solutions that can achieve speeds comparable or exceeding that of their classical analytic imaging counterparts while simultaneously providing improved reconstruction performance.
Current model-based image reconstruction provides the state-of-the art algorithms for reconstructing images from noisy or limited measurement data. Such techniques typically work by combining the measurement data with strong prior information on the image structure. However, the resulting optimization problems tend to be much more computationally expensive to solve than more classical analytic imaging solutions. Recently neural network solutions appear to be able to compete with such techniques at a much-reduced complexity. However, neural networks require extensive training with large quantities of data and provide black box solutions without clear guarantees on the quality of the reconstruction. This research will take inspiration from these recent neural network solutions as well as advances in the theory of sublinear time sparse reconstruction algorithms to develop new solutions that are both fast and with performance guarantees. In the course of the work exemplar imaging applications such as electron-optic, radar and 3D/4D tomography will be considered.
