TRANSCRIPT

ECE 188: Image and video restoration

Course outline

I Introduction to inverse problems in image/video restoration contexts:denoising, deblurring, super-resolution, tomography, compressed sensing

I Fundamentals of linear/local filtering:maximum likelihood, spatial averaging, heat equation, low-pass and Wiener filtering

I Basic of non-linear filtering:signal adaptation, maximum a posteriori, wavelets and sparsity, non-locality, patches

I Towards advanced filtering:dictionary learning, convex and non-convex optimization, parameter selection

I Lab work covering the implementation of such techniques in Matlab.
