Probability mapping images in dynamic speckle classification
(Optical Society of America, 2013-02)
We propose the use of a learning procedure to identify regions of similar dynamics in speckle image sequences that includes more than one descriptor. This procedure is based on the application of a naïve Bayes statistical ...
Characterization of bio-dynamic speckles through classical and fuzzy mathematical morphology tools
(Elsevier Science, 2013-07)
In this paper we characterize dynamic speckle signals, obtaining selective information through the differentiation of morphological patterns of the temporal history of each pixel, using the morphological granulometric ...
Q-statistics in dynamic speckle pattern analysis
(Elsevier, 2012-06)
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 ...
Tuneable algorithms for tracking activity images in dynamic speckle applications
(Elsevier, 2020-06)
Herein we present a generalized algorithm for processing activity images. Existing algorithms are applicable only to particular cases, and a new, broader approach is therefore proposed here that is based on a set of tuneable ...
Analysis of strawberry ripening by dynamic speckle measurements
(SPIE, 2013-11)
This work seeks to determine the age of a fruit from observation of its dynamic speckle pattern. A mobile speckle pattern originates on the fruit's surface due to the interference of the wavefronts reflected from moving ...
