Joint reconstruction-segmentation on graphs

In most practical image segmentation tasks, the image to be segmented will need to first be reconstructed from indirect, damaged, and/or noisy observations. Traditionally, this reconstruction-segmentation task would be done in sequence: first apply …

Inverse Problems, Krylov Methods, and Dog Pictures

Solving inverse problems in imaging can be very challenging due to the inherent ill-posedness and high dimensionality. To deal with this, one often employs efficient regularisation methods that enforce some additional known properties of the …
