摘要
介绍一种依赖时间的新模型来解决图像除噪音和除模糊问题.分别使用逆反射、中值两种边界条件的数值试验比较本文新模型和Rudin_Osher_Fatemi模型.试验结果表明中值边界条件的误差比逆反射边界条件误差小.
A time dependent model for deblurring and denoising problems is proposed. Comparisons with the Rudin-Osher- Fatemi model are made in numerical experiments with antirefleefive boundary conditions and medium boundary conditions. The results demonstrate that the error with medium boundary conditions is smaller than that with antirefleefive boundary conditions.
