Description: 使用C++编程语言，开发了“单壁碳纳米管手性矢量识别系统”软件。软件处理结果显示:采用最大类间方差法二值化单壁碳纳米管STM图像，能够保留较多单壁碳纳米管的六边形拓扑结构信息；采用本文设计的射线探测加权法能够快速、准确的识别出六边形碳环的中心。-The processing result with the software indicated more topology structure information could be reserved, when maximal variance between-class method and minimum bias-normal distribution index method were employed to binarize the STM images of SWCNTs. We designed detect weighing method, which was adopted to recognize the centers of hexagon rings rapidly. Platform: |
