| Abstract: | Based on the one-dimensional convection-diffusion equation, theconception of image convolution by finite-difference schemes is introduced and ana-lysed. Mechanism and regularity for implementing image enhancement such as smoo-thing and sharpening on the finite-length digital signal are also presented. Theconclusion made by this paper has been applied to studies in the two-and three-dimensional image processing. |
