本文提出一种基于边缘自适应小波变换的多尺度图像修复算法,对非纹理图像有比较好的修复效 果。边缘自适应小波变换的基本思想是,先检测出图像的主要边缘,这些边缘把图像分割成几个平滑区,然后 对图像进行不跨越边缘的小波分解,即在各平滑区内部进行小波变换,得到图像的多尺度表示,并且同时计算 边缘的多尺度表示。这样的小波分解使高频信息基本都集中在边缘上,而高频系数则非常稀疏,而且都接近 于零。在此基础上进行图像修复,就只需要对低频部分与边缘图像进行修复,然后重构得到修复图像即可。 经过小波分解,低频部分破损区域大大缩小,用比较简单的插值方法就可进行修复,大大降低了计算量。对边

这个程序只合适计算k=1 (也就是Lcd=1),对于其他k值,一些参数要做适当变化。这也是soliton format 不宜用于非线性耦合开关的一个原因。它使问题复杂化。这个程序是计算孤子格式化下的非线性薛定格方程组,程序中的方程与我们之前的博文提供的程序的方程不同。我们当初做这个仿真的目的,一方面要重复 S. Trillo, S. Wabnitz, E. M. Wright and G. I. Stegman, 在他们论文“Soliton switching in fiber nonlinear directional couplers.” Opt. Lett. Vol.13, No.8, pp672-674(1988) 的仿真结果,以确保我们程序是正确的。另一方面要以己之矛攻己之盾。当时,孤子开关用孤子归一化的非线性薛定格方程描述已经广泛被接受和使用。很多人因为他们孤子开关的工作,也获得了重要的学术地位,要想发一篇跟他们之前的工作不同的观点的文章是很困难的。那些审稿的人,不是他们本人,就是学生或粉丝。图1中的曲线跟我们其它文中的曲线有很大不同,这是因为在这里输入脉冲是bsech(bt),因而输入脉冲的脉宽跟脉冲幅度一起变化,而其他地方我们只考虑脉冲幅度的变化,因为脉宽的变化已经包含在参量Lcd 中了。
