Abstract

The concept of constrained connectivity [Soille 2008, PAMI] is summarised. We then introduce a variety of measurements for characterising connected components generated by constrained connectivity relations. We also propose a weighted mean for estimating a representative value of each connected component. Finally, we define the notion of spurious connected components and investigate a variety of methods for suppressing them.
