Parallel algorithms for erosion and dilation of label images.

Abstract

It is sometimes useful to be able to apply binary morphological operations, such as erosions and dilations, to labelled images in a fashion that preserves the labels. This article introduces a specialised class implementing parallel methods described in beare et al [2011] that provide very fast dilations by circles and spheres of arbitary size. Comparisons with other implementations using currently available building blocks are also made.
