图像处理中的PDE及其数值解算方法
Numerical Calculating Methods of PDE in Image Processing
摘要
Abstract
Starting with the application in image smoothing, the PDE (Partial Differential Equations) that commonly used in image processing was classified through analyzing the selective diffusive model P-M which proposed by Perona and Malik that was used for conserving edge. The numerical calculating process summed by scholars domestic and aboard specific to the PDE belonging to the type of heat conduction equation was programmed, the numerical calculating method of model P-M was improved, and the stability of solution was proved by utilizing the theory of Maximum and Minimum of PDE.关键词
