A method for the segmentation of images based on thresholding and applied to vesicular textures

no code implementations4 Dec 2016 Amelia Carolina Sparavigna

In image processing, a segmentation is a process of partitioning an image into multiple sets of pixels, that are defined as super-pixels.

Shannon, Tsallis and Kaniadakis entropies in bi-level image thresholding

no code implementations23 Feb 2015 Amelia Carolina Sparavigna

The maximum entropy principle is often used for bi-level or multi-level thresholding of images.

Bi-Level Image Thresholding obtained by means of Kaniadakis Entropy

no code implementations16 Feb 2015 Amelia Carolina Sparavigna

In this paper we are proposing the use of Kaniadakis entropy in the bi-level thresholding of images, in the framework of a maximum entropy principle.

Gray-Level Image Transitions Driven by Tsallis Entropic Index

no code implementations14 Feb 2015 Amelia Carolina Sparavigna

The maximum entropy principle is largely used in thresholding and segmentation of images.

Extracting Networks of Characters and Places from Written Works with CHAPLIN

no code implementations18 Feb 2014 Roberto Marazzato, Amelia Carolina Sparavigna

After this choice, the tool allows the user to enter some parameters, and, according to them, creates a network where the nodes are the characters and places, and the edges their interactions.

Edge-detection applied to moving sand dunes on Mars

no code implementations24 Aug 2013 Amelia Carolina Sparavigna

Here we discuss the application of an edge detection filter, the Sobel filter of GIMP, to the recently discovered motion of some sand dunes on Mars.
