Image alignment is a problem for computing a transformation matrix so that on applying that transformation to an input image, it can be converted to the target image plane. As a result, the resulting images look like they are stitched together and form a continuous larger image.
Panorama is one such example of aligning images, where we collect images of a scene with changing camera angles and the resulting image is a combination of images aligned. A resulting image is as shown, as follows:
In the preceding figure, an example of panorama creation is shown. Using a camera, we collect multiple images for the same scene by adding overlapping regions. As the camera is moved, often, the pose changes significantly, so therefore for different poses of the camera a transformation matrix is computed.
Let's get started with a basic method...
