The subtracted image needs to be scaled, if 8-bit channel is used to display the subtracted images. So, the method of adding 255 to each pixel and then dividing by 2, has certain lim its. What is/are those lim its?

The subtracted image needs to be scaled, if 8-bit channel is used to display the subtracted images. So, the method of adding 255 to each pixel and then dividing by 2, has certain lim its. What is/are those lim its? Correct Answer The truncation inherent in division by 2 causes loss in accuracy

The given method is quite simple and easy to implement, however it has the lim itation of accuracy loss because of truncation inherent in division by 2 and also that it doesn’t ensure the full range usage.
