Embodiment Construction
[0055] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0056] To realize the more accurate image registration provided by the present invention, a new image registration model needs to be established first. The optical flow field registration model based on the variational method is mainly composed of two parts: the depolarization variational framework and the regularization term energy term. In view of the disadvantage that the offset field easily leads to low registration accuracy of the traditional registration model, the present invention combines the debiasing field and the optical flow field into a unified variational framework, so that the two complement each other. In view of the fact that the global regulari...
