Abstract

A pyramid approach is developed and implemented for reconstructing binary patterns from two orthogonal projections. The binary patterns are first reconstructed in a lower spatial resolution and then refined from level to level in the pyramid structure with an improving spatial resolution. The algorithm is compared with a model-based algorithm, which reconstructed the binary patterns directly in the required resolution. The performance of the pyramid algorithm is investigated from the viewpoint of processing speed and reconstruction quality. It is concluded that the multiresolutional image-reconstruction technique is superior to direct methods
