Question

Process of changing pixel intensity value to achieve consistency in dynamic range is known as

Answer 1

In order to answer this question one must have little concept of image processing. In context to image processing there is a process called normalisation by the help of which we can change pixel intensity value in order to achieve consistency in dynamic range.

The process is also called as dynamic range expansion and it is basically applied on photographs that are having poor contrast. Normalisation helps to avoid fatigue.

There are various formulas for normalisation where the max and min range changes for the final value.

For example we can consider the formula for Linear normalisation:

I n = (I - Min)((newMax - newMin)/(Max - Min)) + newMin
