最小生成树问题 问题描述：若要在ｎ个城市之间架设通讯网络，只需要架设ｎ－１条线路即可。如何以最低的经济代价建设这个通讯网，是一个网的最小生成树问题。 设计要求：利用克鲁斯卡尔算法求网的最小生成树；以文本形式输出生成树中各条边以及它们的权值。 -The issue of minimum spanning tree problem Descr iption: n To set up a communication network between cities, only need to

The frequency domain plays an important role in image processing to smooth, enhance, and detect edges of images. Although image data typically does not include imaginary values, the fast Fourier transform (FFT) has been used for obtaining spect

a new mathematical and algorithmic framework for unsupervised image segmentation, which is a critical step in a wide variety of image processing applications. We have found that most existing segmentation methods are not successful on histopa
