       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

LDPC码即低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域.现给出LDPC码的BP译码算法实现。

可以运行，分割效果好，分割彩色图像，适合初学者理解聚类分割的原理和方法，简单易懂，十分好用k-means算法，也被称为k-平均或k-均值，是一种得到最广泛使用的聚类算法。它是将各个聚类子集内的所有数据样本的均值作为该聚类的代表点，算法的主要思想是通过迭代过程把数据集划分为不同的类别，使得评价聚类性能的准则函数达到最优，从而使生成的每个聚类内紧凑，类间独立。这一算法不适合处理离散型属性，但是对于连续型具有较好的聚类效果。
