WebThe catch is that, unlike classical regularization (e.g. Tikhonov), the matrix Q is data-driven-it is computed from the observed image via a kernel (affinity) matrix. For linear restoration problems with quadratic data-fidelity (e.g. superresolution and deconvolution), the overall optimization reduces to solving a linear system; this can be ...
