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. 2010 IEEE.
