View images in more detail to find visual elements common to both images.
Use the Control Point Selection Tool to pick control points in the image to be registered and the fixed image.
Fine-tune your control point selections using the
Save control point pairs in the workspace to make them available for the next step in image registration.
To save the current state of the Control Point Selection Tool, choose the Export Points to Workspace option from the File menu.
Image registration aligns images by applying geometric transformations.
Pick corresponding points in a pair of images to determine the parameters of a registration transformation.
To specify control points in a pair of images you want to register,
use the Control Point Selection Tool,
The Image Processing Toolbox™ provides functionality for applying geometric transformations to register images.
