title: Automatic digital processing in speckle photography: comparison of two algorithms.
abstract: Two algorithms for analyzing speckle photography fringes for spacing and orientation using a digital image processing system are compared. Each algorithm was tested for accuracy and computer run-time through a computer simulation which includes the degradation of data by noise.
