This article first give the concept of the scale space, and construct the relationship between the heat conduction equation and the Gaussian scale space, which lead to the partial differential equations. Then the article introduces linear diffusion equation, nonlinear isotropic diffusion and the nonlinear an isotropic diffusion. After analyze the connection between nonlinear filters and an isotropic...
This article mainly study the application of the digital image process based on PDE. We present the concept and property of scale space, and give the relationship between continuous scale space and the PDE model, for example, the heat exchange equation ascertain the gauss scale space. Following with the simple linear diffusion equation, it introduces the nonlinear isotropic diffusion and the nonlinear...
