Border Propagation: A Novel Approach to Determine Slope Region Decompositions (2020) – Research Unit Virtual & Augmented Reality

Abstract

Slope regions are a useful tool in patternrecognition. We review theory about slope regionsand prove a theorem linking monotonic paths and theconnectedness of levelsets. Unexpected behavior ofslope regions in higher dimensions is illustrated bytwo examples. We introduce theborder propagation(BP) algorithm, which decomposes ad-dimensionalarray (d∈N) of scalar values into slope regions. Itis novel as it allows more than 2-dimensional data.
