This paper studies the partial differential equations in the digital image processing applications. The article first elaborates the concept of scale space and nature, and to determine the heat conduction equation by the Gaussian scale space is given as an example a continuous scale space with the associated partial differential equations. Then a simple article from the beginning of the linear diffusion equation, introduce a non-linear homogeneous proliferation and the proliferation of non-linear heterogeneous, not only the corresponding specific diffusion equation model, but also for them to deal with different image effects were comparison.
