Image registration has traditionally been done using two distinct approaches:
learning based methods, relying on robust deep neural networks, and
optimization-based methods, applying complex mathematical transformations to
warp images accordingly. Of course, both paradigms offer advantages and
disadvantages, and, in this work, we seek to combine their respective strengths
into a single streamlined framework, using the outputs of the learning based
method as initial parameters for optimization while prioritizing computational
power for the image pairs that offer the greatest loss. Our investigations
showed that an improvement of 0.3\% in testing when utilizing the best
performing state-of-the-art model as the backbone of the framework, while
maintaining the same inference time and with only a 0.8\% loss in deformation
field smoothness.

本研究旨在将学习方法和优化方法结合，使用学习方法的输出作为优化的初始参数，并根据图像对的损失进行计算，从而在保持相同推理时间和形变场平滑度仅降低 0.8% 的情况下，通过使用最佳性能的先进模型作为框架的骨干，在测试中获得了 0.3% 的改进。
