Embodiment Construction
[0075] An image registration method based on modal transformation of differential homeomorphic demons, such as figure 1 shown, including the following steps:
[0076] Step S110: Perform affine transformation on the reference image and the floating image to generate an initial spatial transformation.
[0077] Affine transformation is a linear transformation that maintains the "straightness" and "parallelism" of two-dimensional graphics. "Natural" means that the relative positional relationship between two-dimensional graphics remains unchanged, parallel lines are still parallel lines, and the positional order of points on a straight line remains unchanged. Affine transformations can be implemented by a combination of a series of atomic transformations, including translation, scaling, flipping, rotation, and tangent.
[0078] Step S140: Perform modal conversion on the affine transformed reference image and the affine transformed floating image.
[0079] Specifically, as fig...
