Arithmetic with images

In this section, we will learn about some common arithmetic operations that can be performed on images, such as bitwise operations, addition, and subtraction, among others. In connection with these operations, one key point to take into account is the concept of saturation arithmetic, which is explained in the following subsection.

Saturation arithmetic

Saturation arithmetic is a type of arithmetic operation where the operations are limited to a fixed range by restricting the maximum and minimum values that the operation can take. For example, certain operations on images (for example, color space conversions, interpolation techniques, and so on) can produce values out of the available range. Saturation...
