The method firstly selected Fourier spectrum energy ratio and gray contract which were extracted from fingerprint image sub-blocks to construct feature vectors,and then classified these feature vectors by linear support vector machine,finally performed morphological operations to ultimately realize fingerprint image segmentation.
该方法首先选择指纹图像子块的傅里叶频谱能量比和灰度对比度构成特征向量,利用线性支持向量机对这些特征向量进行分类,再运用二值图像形态学操作最终实现指纹图像分割。
In this research,the authors used Fourier transform infrared spectroscopy(FTIR) and two-dimensional correlation infrared spectroscopy(2D-IR) to determine fine sea cucumber products.
作者采用傅里叶变换红外光谱法(FTIR)和二维相关红外光谱技术(2DIR)对海刺参粉末进行分析,得到了自制海刺参粉的谱图,然后以此为标准对五个不同厂家的海刺参胶囊进行相关性比较,结果显示大连海晏堂的海刺参胶囊与作者自制的鲜活冻干样品最为相符,这表明它基本上是纯的冷冻干燥海刺参粉;实验还表明通过建立标准红外谱图库来监控海刺参产品质量、制定统一标准是完全可能的。
