CutESC: Cutting edge spatial clustering technique based on proximity graphs

作者:

Highlights:

• We propose a cut-edge algorithm for spatial clustering (CutESC) based on proximity graphs. The CutESC algorithm removes edges when a dynamically calculated cut-edge value for the edge’s endpoints is below a threshold.

• The dynamic cut-edge value is calculated by using statistical features and spatial distribution of data based on its neighborhood.

• The algorithm works without any prior information and preliminary parameter settings while automatically discovering clusters with non-uniform densities, arbitrary shapes, and outliers.

• There is also an option which allows users to set two parameters to better adapt clustering solutions for particular problems.

• Experiments have been conducted on various two-dimensional synthetic data and image segmentation to assess advantages of the CutESC algorithm.
