基于线性各向异性偏微分方程的图像放大法

Image zooming based on linear anisotropic partial differential equations

在分析图像特点以及常规插值方法放大图像一些不足之处的基础上,注意到有关偏微分方程图像插值理论及其应用,提出一种全新的偏微分方程图像放大方法:基于线性各向异性偏微分方程的图像放大法,并通过实验证明,该方法是一种非常快速且效果极好的图像放大方法.

After analyzing some deficiency in conventional image interpolation methods in image zooming,noticing the application of partial differential equations in the theory of image interpolation,we present a new model,which based on the boundary value problem of anisotropic parabolic equations,for image zooming.Experimental results show that the method can work fast on the image zooming and reach better quality of zoomed image.
