6. Image Arithmetic

Chapter 6. Image Arithmetic

As discussed in Chapters 3 and 4, we can think of images as a grid of pixels with each pixel having a color defined as an RGB triplet. Each component in that RGB triplet has a value in the range of 0 to 255. Given this structure and format, it is actually quite easy to perform arithmetic on images, such as addition, subtraction, multiplication, and division. This concept should not be entirely new. Chapter 5 already introduced this idea when using color to segment images. The goal of this section is to examine this concept in further detail, and understand how mathematical manipulation of images is used in a vision system. Topics include:

  • The basic mathematical operations from elementary school, as applied to images
