为了提高图像去噪效果,提出了基于Contourlet域HMT模型的cycle Spinning去噪方法。首先将待去噪图像进行循环平移,使用Contourlet域HMT模型对平移后的图像进行降噪处理,然后将降噪后的图像进行循环反平移,最后将不同循环平移量下的降噪图像进行平均处理,以减少去噪后图像的失真。实验结果表明,该方法不仅可以提高降噪后图像峰值信噪比,而且可以提高降噪后图像的视觉效果。

Write a program to decide if a graph has a cycle or not. The given graph can be a directed or undirected graph, which is indicated at the time of reading the input (0 for directed graph and 1 for undirected graphs). The input is given as an adjacency list.
