Abstract

The paper describes the possibilities of using Fourier-Mellin transform for registering images of holographic interferograms. Registered holographic images will then allow automating their evaluation. Registration based on changes in image intensities using the discrete integral transforms was selected of the methods of registration. Whereas it was necessary to register the images, which are not only translated, but also rotated and with the changed of scale, the Fourier-Mellin transform was used. Use of the image discrete transforms is original in this field, proposed processing algorithm contains also simplified mean of calculating the angle of rotation of the test image instead of common Fourier-Mellin transformation method sequence.
