macro:affine_consistent_elastic_registration

Affine + Consistent Elastic 2D Image Registration

This macro aligns a stack of images taking the first image as reference in two steps: MOPS and bUnwarpJ. The parameters from both methods are introduced in a common dialog.

Requirements

You need to have previously installed the plugins SIFT/MOPS from Stephan Saalfeld and bUnwarpJ from Ignacio Arganda-Carreras.

Input

Stack of 8, 16, 32-bit or RGB-Color images.

Output
  • Aligned stack.
  • Masks stack.
Authors
  • Marta Rivera-Alba
  • Ignacio Arganda-Carreras
Version and updates

March 11th, 2009: updated to be used with bUnwarpJ 2.5.

November 10th, 2008: changed “divergency_weight” to “divergence_weight” in order to run bUnwarpJ last release.
