Image Quality Enhancement Model and its Application Based on PDE

Partial differential equations application in digital image processing is developing rapidly in recent years. The method aim to establish a mathematical model with the partial differential equation, and the model will change the image based on partial differential equation and eventually get the expected effect on the image. Through the processing method with partial differential equation, the image can get the effect unattainable by traditional method. Based on the research result both domestic and abroad, this paper mainly illustrates the establish, analysis and realization of an image enhancement model with PDE. By testing the PDE model with the real image enhancement process, the validity of this method has been verified.
