The image analysis process for sample identification and color extraction applied to an example image. The subfigures on the left show the different main steps involved. a sample grid and midpoint identification, c sample extraction, and e sample image trimming. The subfigures b, d, and f show the results of each of these three main steps. g examples of extracted RGB color intensities. h the RGB intensity differences (ΔRGB) when using the bottom sample of each column as the reference for the rest of the column samples
