Image Enhancement Method Based on Nonlinear Partial Differential Equations
To improve image quality of the uneven illumination images,low-brightness images or high-brightness images,the algorithms of the partial differential equation image enhancement are studied. According to the theory of partial differential equation image enhancement,improve the method of image enhancement based on existing partial differential equation,which can enhance the Brightness and contrast of the image vary well. Discrete equations using the finite difference method,combined with the heat equation. Calculation is simple,fast,for the realization of real-time video image enhancement processing has provided a guarantee. The algorithm can be used widely,can achieve good visual effects on image enhancement and Real-time processing requirements.
