Abstract: Amethod has been proposed for the remedy of the information loss at the marginal belts in 2D-convolution.Theoretical study shows that the 2D-convolution integers for noncentral point evaluation can be found just by using linear combination of those for the central points.New integers acquired ensure that the information loss would not happen while doing derivation with 2D-experimental data array.The related items concerning the symmetry of these integers and the importance of identifying all convolution parameters were also discussed.

Key words: Data truncation, Information remedy, Noncentral point convolution integers, Linear combination
