A Generator for 2D Moving Regions

Abstract

One of the main challenges in investigation in the field of spatiotemporal databases is that there are few datasets available, they represent specific phenomena, in general, have a small number of observations, and do not provide a ground truth. In this work we present a generator for 2D moving regions that can represent several atomic events: face shrink, grow and evolve, face burst and engulf, face internal split from a closed and an open line (fissure), face internal merge, face split at a point, face split hole, face consume hole, hole shrink, grow and evolve, hole appear from an open line, hole consume face, hole split face, and hole split at a point. The generator allows datasets to be created and annotated automatically and it can also be used to create custom datasets. We also present datasets created with this generator.
