New similarity index based on entropy and group theory

no code implementations28 Oct 2014 Yasel Garcés, Esley Torres, Osvaldo Pereira, Roberto Rodríguez

In this work, we propose a new similarity index for images considering the entropy function and group theory.

Application of the Ring Theory in the Segmentation of Digital Images

no code implementations17 Feb 2014 Yasel Garcés, Esley Torres, Osvaldo Pereira, Roberto Rodríguez

This new index was applied as a new stopping criterion to the Mean Shift Iterative Algorithm with the goal to reach a better segmentation.

A new stopping criterion for the mean shift iterative algorithm

no code implementations8 Nov 2013 Roberto Rodríguez, Esley Torres, Yasel Garcés, Osvaldo Pereira, Humberto Sossa

This paper proposes a new stopping criterion for the mean shift iterative algorithm, where stopping threshold via entropy is used now, but in another way.
