1)  ringing artifact
边缘振荡效应
1.
Previously published techniques usually perform well on small magnifications, however, as magnification increases, they suffer two severe problems: one is the exponentially increased computational complexity, the other is the degradation of reconstruction quality caused by severe ringing artifacts.
一般的超分辨率图像重构算法在小放大倍数时效果比较好,但当放大倍数上升时,存在两个问题:一个是计算复杂性的急剧上升,另一个是边缘振荡效应的加剧导致成像质量迅速恶化。
2.
Due to the disa-bility of handling different regions of the image,previously published MAP super-resolution image reconstruction techniques generally produced severe blurred image or image with severe ringing artifacts.
已有的MAP超分辨率图像重构算法由于没有对图像中的不同区域分别处理,所以无法在重构出清晰的边界和更多细节的同时抑制边缘振荡效应的产生。
3.
However,due to the ill-posed nature of the super-resolution image reconstruction,the ringing artifacts can not be easily removed in the reconstruction process.
但是,由于超分辨率图像重构本身是一个病态求逆过程,在重构图像中所产生的边缘振荡效应往往很难在重构过程中予以消除。

补充资料:边缘效应
分子式:
CAS号:

性质:一)在薄层色谱中,当使用混合溶剂展开时,有时会出现同一组分在薄层中部比在薄层两边缘处移动慢的现象,即中部的Rf值比边缘的Rf值小,这种现象称边缘效应。这是由于容器中展开剂蒸气未达饱和造成的。(二)摄影影像的明暗边界处出现的一种显影效应,在强曝光量一侧,密度进一步增加时,在弱曝光量一侧密度进一步减小。这是分界处两边的显影剂和显影抑制剂浓度差引起的相互扩散作用造成的。显影时充分搅拌能降低此效应。彩色胶片中添加能释放显影抑制剂的功能性化合物可人为地增强边缘效应,边缘效应的增强有利于提高影像的锐度。
