Research profile

Barend's research interests are mainly in the application of computational strategies and techniques to solve geographical problems (i.e. geocomputation). As part of his PhD, he is investigating the use of convolutional neural networks (CNN) to classify barchan images into categories of increasing asymmetry. This is part of a larger project which aims to greatly reduce the amount of time that researchers have to spend in collecting barchan morphometric data from satellite imagery.
