DTMF(Dual Tone Multi Frequency)Recognition Algorithm
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

sift算法
应用背景本文提出了一种从图像中提取独特不变特征的方法,可用于完成不同视角之间目标或场景的可靠匹配的方法。这种特点对图像的尺度和旋转具有不变性。并跨越很大范围的对仿射失真,三维视点的变化,添加的噪音和光照变化的图像匹配具有鲁棒性。关键技术
通过将个别特征与由已知目标特征组成的数据库进行快速最近邻算法的匹配,然后使用Hough变换来识别属于单一目标的聚类(clusters),最后通过最小二乘解执行一致的姿态参数的核查确认。这种识别方法可以在有力确定对象之间的聚类和遮挡的同时实现近实时性能。

leach算法
算法基本思想是:以循环的方式随机选择簇头节点,将整个网络的能量负载平均分配到每个传感器节点中,从而达到降低网络能源消耗、提高网络整体生存时间的目的。仿真表明,与一般的平面多跳路由协议和静态分层算法相比,LEACH分簇协议可以将网络生命周期延长15%。
