Abstract
Introduction The conventional deconvolution method for two - dimensional image restoration is considered. The algorithm of conventional deconvolution method in basis of Hadamard transformation is proposed.The problem statement The examples of standard image restoration by conventional deconvolution method in Hadamard transformation field with different level of additive noise are given. The results of restoration in Fourier and Hadamard transformation fields at the same level of additive noise are shown for comparison.Conclusions Realization of conventional deconvolution method in basis of Hadamard transformation gives the results similar to restoration results using discrete Fourier transformation. Herewith there is no Gibbs effect and basis of Hadamard transformati on is convenient for archiving images. The conventional deconvolution method in Hadamard transformation field is rather simple, requires less computation time and less number of arithmetic operations in comparison with image restoration method in natural coordinates.
