Level set method based segmentation provides an efficient tool for topological and geometrical shape handling, but it is slow due to high computational burden. In this work, we provide a framework for streaming computations on large volumetric images on the GPU. Our streaming computational model allows processing large amounts of data with small memory footprint. We show volumetric segmentation using a higher order, multi-phase level set method with speedups of the order of 5~10 times.
