Recovery for a real image from its Hartley transform modulus only

A new algorithm for the reconstruction of a real image from its Hartley transform modulus only is presented based on the general theory of the amplitude-phase retrieval problem. From our simulating calculation, it is shown that the image reconstruction can be successfully achieved from its Hartley transform modulus only by using the Y/G algorithm. The influence of noise contained in Hartley transform intensity on the convergent solution is also examined in detail.
