Abstract

A data compression and reconstruction technique is presented based on a Fourier transformation. Correlations of up to 99.8% have been achieved between the original and the reconstructed image. In this method the complex Fourier coefficients are calculated and sorted from maximum to minimum. A certain small percentage of these coefficients is retained along with their coordinates. An inverse FFT is used to reconstruct a first approximation of the image and after that algebraic reconstruction techniques are used for refinements on the image.
