We introduce in this project the code to the paper **VoCC: Vortex Correlation Clustering based on masked Hough Transformation in Spatial Databases** together with its experiments.

## Vortex Correlation Clustering
Vortex Correlation Clustering is used to find vortices in two dimensional particles sets which have also a movement vector. For targeted radii the **VoCC** algorithm finds candidates with a Circle Hough Transformation in the two dimensional space and merges them to bigger clusters with our proposed **RDBSCAN** algorithm. This variant of DBSCAN does not need a specified epsilon and uses the radius of each vortex candidate. After identifying vortex candidates we map them back as labels onto the input data.
