Sonnet text - illumination gradient.

args[0] (son1)

The original image.

args[0] (son1thr1)

Result of thresholding son1 at a pixel value of 128.

args[0] (son1sub1)

Result of pixel subtracting son2 from son1 and adding an offset of 100.

args[0] (son1sub2)

Result of pixel subtracting son2 from son1 using wrapping.

args[0] (son1sub3)

Result of pixel subtracting son2 from son1 using absolute difference.

args[0] (son1sub4)
