摘要
MAP方法是解决超分辨率图像复原问题中的一种常用算法,但通常的MAP超分辨率复原方法对于图像的边缘部分没有进行特殊处理,导致最终恢复出来的高分辨率图像的边缘过于平滑。提出了一种局部边缘自适应的先验概率算子,并将其应用于MAP超分辨率图像复原中。与传统方法相比,它具有更好的图像边缘保持能力,因此获得了更佳的视觉效果。
Maximum a posterior is one of the commonly used methods in super-resolution image reconstruction. However, most already offered MAP methods do not consider image edge and yield to smooth edge. In this paper, a method based on adaptive edge preserving prior is proposed. Compared to the traditional methods, the new method can keep good image edge and thus give better visual effect.
