The SpatioTemporal Features eXtractor (stfX) is the prototype implementation of the conceptual framework proposed in my master thesis. It focusess on the quantification of the features of interest occurring over user-inputted spatiotemporal phenomena

microservicesspatiotemporal datadata miningchange detection

The central microservice of the stfX, responsible for everything that is not the computation of spatiotemporal change features. Developed in the context of my master thesis.

JavaSpringBootmicroservicedata transformationspatiotemporal data

A microservice to run the Coherent Point Drift (CPD) method, a point set registration algorithm by Myronenko and Song (2010), to estimate the spatial transformations affecting spatiotemporal phenomena. Developed in the context of my master thesis.
