摘要
本文针对一维对流—扩散方程,引进和分析了用差分格式进行图像卷积运算的概念,并阐述了用于对一维有限数字信号进行光滑和锐化等图像增强的机理及规律。上述结论已被推广用于二维和三维图像处理的研究中。
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.
