Texture descriptor combining fractal dimension and artificial crawlers

Wesley Nunes Gonçalves, Bruno Brandoli Machado, Odemir Martinez Bruno
2014 Physica A: Statistical Mechanics and its Applications  
In this paper, we propose a new method to describe textures using the artificial crawler model. This model assumes that each agent can interact with the environment and each other.  ...  Since this swarm system alone does not achieve a good discrimination, we developed a new method to increase the discriminatory power of artificial crawlers, together with the fractal dimension theory.  ...  Artificial crawlers: N artificial crawler, as those explained earlier, are performed in a texture image.  ...
