摘要
This paper presents iteration algorithms for the interchannel gradient reconstruction of the signals of multicomponent digital images distorted by Z-axis noise. The results of numerical studies show that the distorted elements of multicomponent images are reconstructed more accurately when the proposed algorithms are used than they are when known algorithms are used.
