The Degrees of Symmetry functions
Hector Rabal, Nelly Cap
We propose a generalization of the concept of symmetry as a continuous function of the reference center or line location. We suggest that this concept can be applied to many closed…
Biospeckle signal descriptors: a performance comparison
Ana L. Dai Pra, Isabel L. Passoni, G. Hernan Sendra +2
The characterization of dynamic phenomena using laser speckle has been studied in several applications and many descriptors have been developed to analyze the resulting images. In…
An intuitive introduction to the concept of spatial coherence
Héctor Rabal, Nelly L. Cap, Eduardo Grumel +1
The concept of spatial coherence is usually hard to be understood the first time that it is studied. We propose here a fully intuitive geometric description that does not contain m…
Unsupervised learning segmentation for dynamic speckle activity images
Lucia I. Passoni, Ana I. Dai Pra, Gustavo J. Meschino +4
This paper proposes the design of decision models based on Computational Intelligence techniques applied to image sequences of dynamic laser speckle. These models aim to identify i…
