Combining fractal and deterministic walkers for texture analysis and classification
(Elsevier BVAmsterdam, 2013-11)
In this paper,we present a novel texture analysis method based on deterministic partially self-avoiding walks and fractal dimension theory. After finding the attractors of the image (set of pixels) using deterministic ...
Texture descriptor based on partially self-avoiding deterministic walker on networks
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-11-01)
Texture image analysis is an important field of investigation that has attracted the attention from computer vision community in the last decades. In this paper, a novel approach for texture image analysis is proposed by ...
Texture analysis based on maximum contrast walker
(ELSEVIER SCIENCE BV, 2010)
Recently, the deterministic tourist walk has emerged as a novel approach for texture analysis. This method employs a traveler visiting image pixels using a deterministic walk rule. Resulting trajectories provide clues about ...
Texture analysis using graphs generated by deterministic partially self-avoiding walks
(ELSEVIER SCI LTD, 2011)
Texture is one of the most important visual attributes for image analysis. It has been widely used in image analysis and pattern recognition. A partially self-avoiding deterministic walk has recently been proposed as an ...
Influence of memory in deterministic walks in random media: Analytical calculation within a mean-field approximation
(AMER PHYSICAL SOC, 2008)
Consider a random medium consisting of N points randomly distributed so that there is no correlation among the distances separating them. This is the random link model, which is the high dimensionality limit (mean-field ...
Crossover between the extended and localized regimes in stochastic partially self-avoiding walks in one-dimensional disordered systems
(AMER PHYSICAL SOC, 2010)
Consider N sites randomly and uniformly distributed in a d-dimensional hypercube. A walker explores this disordered medium going to the nearest site, which has not been visited in the last mu (memory) steps. The walker ...

Consider N sites randomly and uniformly distributed in a d -dimensional hypercube. A walker explores this disordered medium going to the nearest site, which has not been visited in the last μ (memory) steps. The walker ...
