Clasificación de células cancerígenas mediante dimensión fractal
, 2022 “Para explicar los fenómenos geométricos de la naturaleza, la geometría euclidiana no puede dar una explicación acertada a todo, para ello la geometría fractal se encarga en gran medida de esto: da un entendimiento de la rigurosidad de la naturaleza, que

Toward reduction of artifacts in fused images
, 2011 Most fusion satellite image methodologies at pixel-level introduce false spatial details, i.e.artifacts, in the resulting fusedimages. In many cases, these artifacts appears because image fusion methods do not consider the differences in roughness or ...

Fractal Analysis on Asphalt Mixture Using a Two-Dimensional Imaging Technique
Advances in Materials Science and Engineering, 2016 Fractal is a mathematical set that has a fractal dimension which usually exceeds its topological dimension and may be nonintegral. Since the asphalt pavement texture has limitations of randomness and self-similarity, fractal theory has been explored to ...
