摘要
在图像超分辨方法中,经典插值方法存在块状效应和图像模糊的情况,而以经典插值方法为基础,用偏微分方程进行后处理的方法则较为复杂。运用各向同性方程与各向异性方程进行耦合得到了一个新的偏微分方程模型,用该模型对图像进行超分辨处理,既降低了计算复杂度,又能保证得到较好的图像超分辨效果。实验结果表明了本文方法的优越性。视觉感知具有良好的一致性。
In Image super-resolution methods, the classical interpolation methods have checkerboard effect and image blur.Using the partial differential equations with the post-processing is more complicated.In this paper, it is proposed to obtain a new PDE model which is coupled between isotropic and anisotropic partial differential equations.This model is processed for image super-resolution.It does not only decrease computational complexity, but also ensures a better image super-resolution effect.The experimental results show the advantages of this method.
