论文摘要
通常使用具有可变尺度，旋转和翻译的多个不同显微镜方法测量单个样本。由于缺乏未准备好的底物的关键点，因此在二维材料的高光谱图像中特别困难。识别这些样品应变中的变化可以通过创建关联图像的关键来帮助对这些样品进行注册。这些图像的注册可以通过将多个图像对准单个坐标空间来从这些各种仪器进行多模式分析。这是通过Hough转换和任意分辨率定义来生成新的坐标框架来完成的，在该坐标框架中可以通过像素来保留空间信息并以像素为基础的像素。这种多模式图像对齐方式可用于将来自各种仪器的数据关联。从拉曼光谱中提取应变信息，并使用所得的高光谱图像以其他显微镜模式注册拉曼信息。
It is common to measure a single sample using multiple different microscopy methods that have variable scales, rotation and translation. Registering hyperspectral images of two dimensional materials is particularly difficult due to the lack of keypoints on unprepared substrates. Identifying variations in the strain of these samples can assist in the registration of these samples by creating keypoints to correlate images. Registration of these images allow for multimodal analysis from these various instruments by aligning multiple images into a single coordinate space. This is done by Hough transformations and arbitrary resolution definitions to generate a new coordinate frame where spatial information may be preserved and correlated on a pixel by pixel basis. Such multimodal image alignment may be used to correlate data from various instruments. Strain information is extracted from the Raman spectra and the resulting hyperspectral image is used to register the Raman information with the other modes of microscopy.
