“…The set of master binary templates is derived from the original image, depicted in Fig. 10a, by skeletonizing the image, (Yatagai et al, 1982). The result of skeletonization is shown in Fig.…”

“…Because of this disadvantage, the fringe binary method is not widely used. (4) Peak detection: Peak detection [29][30][31][32][33][34][35][36][37] means finding the local maxima or minima of the grayscale images. In this method, the whole image is SEM subjected to a peak detection matrix and the gray level of the pixels in the matrix is reduced to zero value if a peak does not exist and to logical F1_ if a peak is found.…”

Polycrystalline aluminum alloy is manufactured by annealing, compared to the width of the specimen, the size of the grains can not be omitted, which makes the specimen anisotropic. Under uniaxial tension, the deformation field is inhomogeneous. In this study, moiré interferometry is successfully applied to measure the deformation of the polycrystalline specimen. The experimental results presented the stress versus strain responses of the marked grains in different orientations and different shapes. By using fringe centering method, the strain distributions under certain load in the centers and on the boundaries of the grains are analyzed.

An approach to the interpretation and recognition of images based on the directional field is developed. A model of an image with structure redundancy is introduced. Digital methods for the construction of the directional field, including the method of local quadratic approximation, the spectral method, and the variance method, are considered. An optical scheme for the construction of the directional field with the use of radial segment spatial filters is presented. The developed approach is tested in the analysis of fmgerprint images, tear crystallograms and interferograms.
