“Sparsity-based image processing”

Date: Thursday, October 18, 2018

I will give a brief tutorial on sparse representation of signals and images using over-complete dictionaries. I will then discuss deterministic and Bayesian sparsity-based methods for image restoration and denoising. Finally, I will present new results on unsupervised spectral unmixing of hyperspectral imaging data using our recently developed multi-channel least angle regression algorithm, a new sparsity-based method.
