3. For an image of unsigned bytes, how can it be contrast-reversed? A Subtract each pixel from 255 B Subtract each pixel from 127 C Negate each pixel D Subtract 255 from each pixel
The way to find this is to look at the colour wheel and draw a line across it from green — you will find that the colour “opposite” it across the wheel is magenta. For an image of unsigned bytes, how can it be contrast-reversed? 255 – 255 = 0 and 255 – 0 = 255, so subtracting from 255 does this.
