Automatic regularization parameter selection: controlled wavelet domain sparsity

Juho Rimpeläinen February 5, 2018

Summary: Choosing the regularization parameter is a hard problem, for which many approaches exist. Here we discuss the recently developed and fully automatic method, called controlled wavelet domain sparsity (CWDS) in the context of X-ray tomography. This approach involves sparsity promoting regularization with respect to an orthogonal wavelet basis. The ( continue reading… )
