Fig. 3From: Localization of polyhydroxybutyrate in sugarcane using Fourier-transform infrared microspectroscopy and multivariate imagingImages of wild-type sugarcane a without and b with spectral points selected. The points in image (b) correspond to the wild-type spectra in Fig. 5a. The images were collected using a 128 × 128 focal plane array detector. c Re-constructed image using the first principal component. d Loadings plot for the first principal component used in re-constructing the image in (c)Back to article page
