RESEARCH_ON_END-TO-END_HANDOFF
说明: 本文在研究IEEE802.16e协议和SIP协议的基础上,提出了利用
SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨
层切换的设计思想,联合MAC层和应用层SIP协议,在底层链路切换
的同时,完成应用层会话的修改,加快了切换过程,减少了切换时延,
提高了切换成功率。本文基于NS2仿真平台,完成了相应的仿真平台
搭建过程,实现了SIP协议模块和WiMAX协议模块的融合,扩展了SIP
协议模块的部分消息,最终在基于SIP协议模块和WiMAX协议的统一
NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建
立和修改过程。

Perform SVM and test results
a) For now, assume that the main script is grid_search.IT performs a grid search for SVM using RBF kernel , for the 2 parameters C and gamma .Criterios for choosing the right values is the F1 score and accuracy of the classifier. b) Having choosen the right parameters , the next step is to convert binary values to probabilities.

edge
在matlab,传统的边缘检测直接调用edge函数,但是得到的边缘信息较稀薄,可以通过将sobel,roberts,prewitt三种算子的边缘检测叠加起来,并且对于连续的边缘部分拓宽,使得边缘更连贯清晰(In matlab, traditional edge detection edge direct call function, but thinner than the edge information can be obtained by sobel, roberts, prewitt three edge detection operator stack up, and for widening the continuous edge portion, so that the edge is more consistent clear)
