title = "Regularization for undersampled ptychography",
abstract = "Ptychography becomes increasingly ill-posed when the overlap between neighboring scan points is reduced, inhibiting the object reconstruction. Here, we discuss and show reconstructions with low-overlap ratios by regularizing with priors such as Total-Variation and Structure-Tensor-Prior.",
