Its performance depends largelyon the seleclion of seed points and growth rules. In order Lo extract snail images with such methods more effectively.The article analyzes the basic idea of the seeded region growing method(SRG) and presents an improved seededregion growing method (ISRG) which is used to extract the snail images. In ISRG, novel similarities rules and anew dynamic threshold method are adopted. For the complex and various habitat of snail, ISRG selects the region growing seed points manually. It is demonstrated by experimental results that ISRG can achieve better snailimage extraction results under the complicated real-world sceneKey words: seeded region growing (SRG; image extraction; dynamic threshold; snail(E D:X, JC1994-2012ChinaAcademicJournalElectronicPublishingHouse.Allrightsreservedhtlp://www.cnki.net

用于分类的SVM的代码，很好用的哦！各种分类情形都有哦！

近年来，在高性能全数字控制的电气传动系统中，作为电力电子逆变技术的关键，pwm技术从最初追求电压波形正弦，到电流波形正弦，再到磁通的正弦，取得了突飞猛进的发展［1］。在众多正弦脉宽调制技术中，空间电压矢量pwm（或称svpwm）是一种优化的pwm技术，能明显减小逆变器输出电流的谐波成分及电机的谐波损耗，降低脉动转矩，且其控制简单，数字化实现方便，电压利用率高，已有取代传统spwm的趋势。本文对空间电压矢量pwm的原理进行了深入分析，重点推导了每一扇区开关矢量的导通时间，并在ti公司生产的dsp上实现三相逆变器的控制，证明了分析的正确和可行性。
