WebThe negative transformation subtracts 255 from the input pixel intensity value and produces that as an output. Mathematically speaking, the negative transformation can be expressed as follows: s=T (r)= (255-r) This means that a value of 0 in the input (black) gets mapped to 255 (white) and vice versa.
