This paper develops a new technique in image restoration and transmission process, where the image size is halved after transforming it to the frequency domain by applying discrete Fourier transform. The conjugate symmetry and mirror property of transformed image spectrums could be utilized by deleting the redundant spectrums from second half image after tracking and keeping the conjugated locations. Those redundant locations are kept using one- to- one relationship. Depending on the halving procedure, the new image size will be divided by two. A reconstructed procedure is created to redistribute the deleted spectrum with their associated locations. The reconstructed image is ready now for restoring again by applying the inverse discrete Fo...
