Deformation Field Smoothness

[brumomento]

Hello Jenyu,

I am doing my Master's project on histology image registration using TransMorph. Since I am working in histology, i need to ensure that the local morphology of the samples is respected. Therefore, I opted to use TransMorph-diff for non-linear transformations. However, it still generates really jagged deformation fields. Could you please point me how to tweak the regularisation values in the config file to make the deformation fields really smooth? Or maybe there is something else I could do?

Hello, I have also encountered this issue. I am doing a 2D image task and the generated deformation field has many small jagged edges. Have you solved this problem? Thank you!

Hello, unfortunately no. I have opted to use the B-spline variation instead with high control point spacing for smooth deformations.

I currently need to obtain the reverse deformation field, but it seems that B-spline variation cannot obtain the reverse deformation field very well, is that right?

您好，很遗憾没有。我选择使用 B 样条变化，而不是使用高控制点间距来实现平滑变形。

Could you kindly share the code for your B-spline registration? I'd really appreciate it!
