Biospeckle descriptors: a performance comparison

Biospeckle patterns are named also "boiling" speckles due to its dynamic appearance. This activity takes place when the sample changes its properties due to diverse causes. This phenomenon is characteristic of biological samples and of the some industrial process. There are many descriptors that have been developed to characterize biospeckle patterns. This paper presents some approaches to compare and evaluate a set of time domain descriptors using a controlled experiment
