Elastix for MATLAB

Elastix wrappers for MATLAB

MelastiX is a collection of wrappers for the open source image registration suite Elastix. Elastix is cross-platform and is normally called from the system command-line (no GUI). MelastiX allows the elastix and transformix commands to be called from within MATLAB as though they are native MATLAB commands. This has the following advantages:

1. The user can feed in MATLAB matrices instead of image file names and get a MATLAB matrix back as a result.

2. Parameters can be passed in as Elastix text files or as an MelastiX YAML file. The latter provides some error-checking options as the type and possible values of the parameters can be checked.

3. Parameter files can be modified by passing an optional structure as a command-line argument. This makes it easy to explore how changing parameters affects registration accuracy.

4. Handles both 2D and 3D data. Examples are only 2D, though.

Requirements:

• You will need to install https://github.com/raacampbell/matlab_elastix
• The image processing toolbox is required to run some of the examples but not to run the registration.
