| Popis: | In many imaging applications only the intensity of the image transform can be observed, and the phase information of the transform is lost. Because the Fourier transform of a real function is complex in general, the phase is needed to reconstruct the real image. On the other hand, the Hartley transform of a real image is always real, and only the sign is lost when the Hartley intensity is recorded. The sign ambiguity is a much less serious defect than the absence of phase knowledge when one is recording the intensity of the Fourier transform of a real image. In this paper, we implement a generalized interative algorithm for reconstructing an image from its Hartley transform intensity. The generalized algorithm is based on the error-reduction and input-output concepts. Programs were developed to implement the algorithm. Results show reconstructed images from their Hartley transform intensity. Also, the performance of the implemented algorithm is monitored during the image reconstruction process. |
