Abstract

In this paper we present a parallel algorithm for the topological watershed, suitable for a shared memory parallel architecture. On a 24-core machine an average speed-up of about 11 was obtained. The method opens up possibilities for segmentation of gigapixel images such as found in remote sensing routinely.
