Proceedings of the Workshop on Computational Topology in Image Context 2010
(2010)
It has been an honor and a pleasure to organize the 3rd International Workshop on Computational Topology in Image Context, CTIC 2010, in Chipiona (Spain), this year, after it was held in Poitiers (France) in 2008 and in ...

Computing The Cubical Cohomology Ring (Extended Abstract)
(Universidad de Sevilla, 2010)
The goal of this work is to establish a new algorithm for computing the cohomology ring of cubical complexes. The cubical structure enables an explicit recurrence formula for the cup product. We derive this formula and, ...

On the Recognition of Tori Embedded in R3
(Universidad de Sevilla, 2010)
Many known algorithms allow us to topologically recognize surfaces in 3D images. However, none of them permits us to distinguish different types of embeddings of surfaces. In this paper, we restrict our study to the case ...

Improved Locally Adaptive Sampling Criterion for Topology Preserving Reconstruction of Multiple Regions
(Universidad de Sevilla, 2010)
Volume based digitization processes often deal with non-manifold shapes. Even though many reconstruction algorithms have been proposed for non-manifold surfaces, they usually don’t preserve topological properties. Only ...

Image Segmentation Inspired by Cellular Models using hardware programming
(Universidad de Sevilla, 2010)
Several features of image segmentation make it suitable for bio–inspired techniques. It can be parallelized, locally solved and the input data can be easily encoded using representations inspired by nature. In this paper, ...

Counting excellent discrete Morse functions on compact orientable surfaces
(Universidad de Sevilla, 2010)
We obtain the number of non-homologically equivalent excellent discrete Morse functions defined on compact orientable surfaces. This work is a continuation of the study which has been done in [2, 4] for graphs.

Combining regular decimation and dual graph contraction for hierarchical image segmentation
(Universidad de Sevilla, 2010)
The Bounded Irregular Pyramid (BIP) is a hierarchical structure for image representation whose aim is to combine concepts from regular and irregular pyramids. The data structure is a combination of the simplest regular and ...

Tracking features in image sequences using discrete Morse functions
(Universidad de Sevilla, 2010)
The goal of this contribution is to present an application of discrete Morse theory to tracking features in image sequences. The proposed algorithm can be used for tracking moving figures in a filmed scene, for tracking ...

Invariant Spectral Hashing of Image Saliency Graph
(Universidad de Sevilla, 2010)
Image hashing is the process of associating a short vector of bits to an image. The resulting summaries are useful in many applications including image indexing, image authentication and pattern recognition. These hashes ...

Topology-preserving perceptual segmentation using the Combinatorial Pyramid
(Universidad de Sevilla, 2010)
Scene understanding and other high-level visual tasks usually rely on segmenting the captured images for dealing with a more efficient mid-level representation. Although this segmentation stage will consider topological ...
