===== Introduction =====
Registration method based on elastic deformations represented by B-splines. The invertibility of the deformations is forced through a consistency restriction. For a quick start, you can have a look at the [[video:aligning:bunwarpj_basic_tutorial|video tutorial]].

===== Features =====
It elastically registers two 2D images (8, 16, 32-bit grayscale or RGB Color).

===== Description =====
bUnwarpJ is an algorithm for elastic and consistent image registration developed as an ImageJ plugin. It performs a simultaneous registration of two images, A and B. Image A is elastically deformed in order to look as similar as possible to image B, and, at the same time, the "inverse" transformation (from B to A) is also calculated so a pseudo-invertibility of the final deformation could be guaranteed. Two images are given as a result: the deformed versions of A and B images.

The algorithm implemented on bUnwarpJ and its technical explanations are detailed on the paper:

===== Installation =====
You must simply download bUnwarpJ_.jar to the Plugins folder of ImageJ, restart ImageJ and there will be a new **"Registration > bUnwarpJ"** command in the Plugins menu.

===== Download =====
You can download the latest version of the plugin with the JAR file [[http://jenkins.imagej.net/job/Stable-Fiji/ws/Fiji.app/plugins/bUnwarpJ_-2.6.1-SNAPSHOT.jar | bUnwarpJ_.jar]]. The source code is available [[http://github.com/fiji/bUnwarpJ | in GitHub]].
