B-Splines Grid

Used for creating a smooth, continuous representation of an image.
Provides a flexible and efficient way to model complex shapes and surfaces.
Allows for precise manipulation and control over image deformations.

Thin Plate Splines

Primarily represent affine transformations.
Include translations, rotations, and scaling.
Offer a way to smoothly map points from one image to another.

Similarity Metrics

Primarily measure how similar two images are to each other.
Help determine the quality of image registration results.
Evaluate how well two images match in terms of their shape, size, and intensity.

Poly Rigid

Primarily used for registering images by minimizing the distance between corresponding points.
Exploits the rigid transformation properties of the image to achieve accurate alignment.
Enhances image alignment by directly aligning specific feature points.

Demons

Primarily represent local deformations.
Capture non-rigid variations in image content.
Allow for the registration of images with more complex and non-linear transformations.

This quiz covers the components and classification of image registration, focusing on the comparison between intensity-based and feature-based methods. It discusses finding the transformation or mapping function, as well as the classification into rigid and non-rigid transformations.
