Edge Detection based on Kernel Density Estimation

Osvaldo Pereira, Esley Torre, Yasel Garcés +1

Edges of an image are considered a crucial type of information. These can be extracted by applying edge detectors with different methodology. Edge detection is a vital step in comp…

New similarity index based on entropy and group theory

Yasel Garcés, Esley Torres, Osvaldo Pereira +1

In this work, we propose a new similarity index for images considering the entropy function and group theory. This index considers an algebraic group of images, it is defined by an…

Application of the Ring Theory in the Segmentation of Digital Images

Yasel Garcés, Esley Torres, Osvaldo Pereira +1

Ring theory is one of the branches of the abstract algebra that has been broadly used in images. However, ring theory has not been very related with image segmentation. In this pap…

A new stopping criterion for the mean shift iterative algorithm

Roberto Rodríguez, Esley Torres, Yasel Garcés +2

The mean shift iterative algorithm was proposed in 2006, for using the entropy as a stopping criterion. From then on, a theoretical base has been developed and a group of applicati…
