Abstract :
In this paper we present a memetic algorithm for the reconstruction of binary images represented on a triangular grid. We define the crossover and mutation evolutionary algorithm operators introduced on this grid. We propose a discrete tomography algorithm which uses a switch and compactness operators for the triangular grid to improve the quality of the image in each generation. The algorithm was tested on some images for its effectiveness.
