Figure 5From: A three-dimensional multivariate image processing technique for the analysis of FTIR spectroscopic images of multiple tissue sectionsTwo views of a 3D univariate chemical map plotting integrated absorbance over the spectral region 1275-1190 cm-1 after baseline correction. Red indicates areas of highest absorption and blue indicates areas of lowest absorption. The view is looking toward the section 1 side of the sampled volume in (a) and towards the section 4 side in (b).Back to article page
