Abstract :
Two dimensional Fourier transform is a powerful tool for image processing, especially in the field of image restoration and filtration. But also it is useful for detection of periodicities at any angle with respect to the image edge. This paper describes the use of two dimensional Fourier transform in the MATLAB environment to compute the length of a wave and the angle between the line that connects points with the same phase and the edge of an image. Several sets of images were processed in order to demonstrate the properties of two dimensional Fourier transform. The results along with description of the main algorithm are presented.
