Visualization of spectral image data. (a–c) Three single-band images and corresponding excitation wavelengths. (d) The image generated when the pixel intensity was summed for each wavelength band in the image cube. (e–g) The images in panels (a)–(c) with their respective false-color look-up tables applied. (h) The resultant image when (e)–(g) were merged. (i) An example region drawn on the merged image. (j) Region-specific statistics generated from the region shown in (i). The solid black line is the mean pixel intensity per wavelength and the dashed red lines are $\pm 1$ standard deviation.
