Abstract
An algorithm of the conditional deconvolutionmethod using as the base of discrete orthogonal Hadamard transformation is presented in the paper. The main task of the proposed algorithm is matrix inversion (quadratic form) of distortionpulse characteristics and image "smoothing" in basis of Hadamard transformation in iterative restorationprocedure. Quick formation opportunities(including in symbolic form) and inversion of this matrix with its rarefaction and operatingopportunities in the field of real numbers are displayed. Image restoration by the conditional deconvolution method based on Hadamard spectra alsoshould be considered as an methodextension of using mathematical tools of multiple transformations. The algorithmhas simple and handyformfor PC programming.
