Bigwarp is a tool for manual, interactive, landmark-based deformable image alignment. It uses the BigDataViewer for visualization and navigation, and uses a Thin Plate Spline implemented in Java to build a deformation from point correspondences.

The interface enables landmark pair placement and displays the effects of the warp on-the-fly.


Bigwarp comes with Fiji. You can access it via Plugins › BigDataViewer › Big Warp, or by modifying this example script.


Open two images in ImageJ, one moving and the other target and navigate to Plugins › BigDataViewer › Big Warp. A dialog will appear prompting selection of the moving and target images.
