The ability to quickly annotate medical imaging data plays a critical role in training deep learning frameworks for segmentation. Doing so image volumes or video sequences is even more pressing as annotating these particularly burdensome. To alleviate this problem, work proposes new method efficiently segment videos using point-wise annotations only. This allows be collected extremely and remai...

We present an efficient block-wise update scheme for the QR decomposition of block tridiagonal and block Hessenberg matrices. For example, such matrices come up in generalizations of the Krylov space solvers MINRES, SYMMLQ, GMRES, and QMR to block methods for linear systems of equations with multiple right-hand sides. In the non-block case it is very efficient (and, in fact, standard) to use Gi...

{ The use of mathematical morphology in low and mid-level image processing and computer vision applications has allowed the development of a class of techniques for analyzing shape information in monochrome images. In this paper these techniques are extended to color images. We investigate two approaches for \color morphology": a vector approach, in which color vectors are ranked using a multiv...
