Abstract :
There are strong ideas about phase information which are essential for description and recognition of images in which the main information of images are concealed in them. In this paper, we demonstrate that Fourier magnitude is enough for reconstruction of an image in which the recognition of objects is possible and the dogmas presented about the information of phase are subjected to suspicion. A recursive algorithm is proposed reconstructing the image by just using the information of Fourier magnitude. Also this could be as a lossy image compression method with a 50% information compression ratio.
