First-order gradient regularisation methods for image restoration: reconstruction of tomographic images with thin structures and denoising piecewise affine images
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsCentre for Mathematical SciencesJesus College, 2016-02-02)The focus of this thesis is variational image restoration techniques that involve novel non-smooth first-order gradient regularisers: Total Variation (TV) regularisation in image and data space for reconstruction of thin ...
