Chapter 6. Working with Image Alignment and Stitching

One limitation of cameras is the limited field of view, often shortened to FOV. Field-of-view is the parameter that defines how much information can be captured in one frame obtained by the camera. So, to capture an image that requires a larger field-of-view, we use image stitching. Image stitching is a method of joining multiple images to form a bigger image that represents the information that is consistent with the original images.

In this chapter, we will take a look at the following topics:

  • Image stitching
  • Image alignment
  • Video stabilization
  • Stereo vision
