In this study, we compare three commonly used methods for hyperspectral image classification, namely Support Vector Machines (SVMs), Gaussian Processes (GPs) and the Spectral Angle Mapper (SAM). We assess their performance in combination with different kernels (i.e. which use distance-based and ...
The synchronous spectrum analysis results showed four autopeaks near 1 650, 1 640, 1 556, 1 540 cm-1, and the cross peaks between the two autopeaks were all positive. The autopeaks intensity analysis results showed that the medium was the turning point of the change of the protein’s ...
Therefore, it is difficult to use traditional calibration techniques for quantitative calculation, such as the peak height and peak area. Adopting multivariate correction method makes terahertz spectrum a fast, simple and widely applicable way to carry out quantitative analysis. In this paper, the ...
