ED-cPSD: Fast Phase-Size Distribution Via Sequential Erosion-Dilation

Abstract

ED-cPSD is an application for calculating continuous pore and particle-size distribution from digital reconstructions and/or image-based structural data. It is based on the erosion-dilation continuous phase-size distribution method, hence ED-cPSD. A continuous size distribution is a measure of the probability density of finding a particle or pore of a certain size. These distributions are of interest in any field of study involving porous media, including but not limited to electrochemistry, petroleum engineering, geology, and food science. The algorithm behind the software provides a computationally efficient way to calculate phase-size distributions for large domains (>10^9 voxels) in regular office computers in a matter of minutes, while also retaining flexibility and computational efficiency for HPC-scale multi-threading. The algorithm is roughly 280 times faster than a previous version on the same task.
