A nonlinear image enhancement algorithm based on partial differential equations
2010
Image enhancement and image de-noising have being the important research contents of image academic and engineering field, and the partial differential equations have been widely applied to computer vision. The paper applies the thoughts of partial differential equations, puts forward a new improved method of image enhancement. This method can enhance not only the dark images but also the bright images, making the details hidden in the dark background and the bright background very clear. The application scope is wider, and the visual effect is better. This paper uses the finite difference method to discrete the partial differential equations, and combines with the heat equation. It calculates simple, runs fast, and provides a guarantee for real-time video image enhancement processing.
