Figure 1

The selected regions of cancer (a1) and noncancer (a2) areas, with the same size and similar brightness. The three-dimensional graphs of RGB basic analysis in cancer (b1) and noncancer (b2) areas and RGB pixel brightness distribution of cancer (c1) and noncancer (c2) areas; the first row is red, the second row is green, and the third row is blue.
