摘要
A methodology to dynamic speckle analysis by using the wavelet transform (WT) is developed. The optimal texture descriptors are determined. The time evolution of the speckle patterns is described through the behavior of the Mahalanobis distance. From the behavior of this distance function, two parameters are defined that characterize the evolution. An example devoted to the drying of paint assessment is presented.
