Light based measurement techniques have largely proven its efficiency on polymer materials. In this study we describe a method based on specific optical techniques for characterization of dental composites. First, a Dynamic Speckle Pattern (DSP) glob

We introduce q statistics concepts to improve the performance of some methods based on the histogram to estimate dynamic speckle activity. It is shown that some improvements are obtained by choosing appropriate q values that have been empirically det

The movement of the microorganisms towards a higher concentration of the chemical attractant is called positive chemotaxis and is involved in the efficiency of chemical degradation. Several studies are focused in this field related to genomics, and t

This paper proposes a method to visualize different regions into image of biospeckle patterns using Self-Organizing Maps. Images are obtained from sequences of laser speckle images of biological specimens. The dynamic speckle is a phenomenon that occ

The aim of this work is to build a computational model able to automatically identify, after training, dynamic speckle pattern regions with similar properties. The process is carried out using a set of descriptors applied to the intensity variations

The biofilms are involved in pathogenesis and antibiotic persistence and resistance. The number of cells of a given species that will adhere to surfaces depends not only on the affinity of the cells but also on their number available for attachment.

In this work we present to methods to evaluate activity in low dynamic speckle patterns. The first one is based on the behavior analysis of the vortices associated to the pattern. The other one consists in binarizing the speckle image. The speckle gr

In this work we present a method to evaluate activity in low dynamic speckle patterns. It consists of binarizing the speckle image and analyzing the displacements and deformations of the resulting speckle grain regions, here called islands. Numerical

We present a dynamic laser speckle method to easily discriminate filamentous fungi from motile bacteria in soft surfaces, such as agar plate. The method allows the detection and discrimination between fungi and bacteria faster than with conventional
