PIRT - Python Image Registration Toolkit.
Pirt provides functionality for image registration. It is the result of my PhD. There is functionality for a variety of image registration algorothms. Most notably pirt provides an easy way to use the Elastix toolkit. Further it implements some algorithms in Cython (Demons and Gravity).
Image registration itself requires several image processing techniques and data types, which are also included in this package:
- pirt.gaussfun - function for Gaussian smoothing and derivatives, image pyramid class
- pirt.interp - interpolation of 1D, 2D and 3D data (nearest, linear, and various spline interpolants)
- pirt.splinegrid - defines a B-spline grid class (for data up to three dimensions) and a class to describe a deformation grid (consisting of a B-spline grid for each dimension)
The registration algoriths are in
Dependencies and installation
Pirt runtime dependencies:
- visvis (for now)
- A working C compiler
pip install pirt(need Cython)
conda install pirt -c pyzo(probably Windows only)
Status and licensing
Pirt should be considered alpha status. The API may change. There are no sphynx docs. There are little unit tests.
Pirt is pretty much research code that I tried to make more or less user-friendly. It needs much more work to turn it into a proper package suitable for broad adoption. Unfortunately, I currently lack the resources to do that. If you have an interest in moving Pirt further, be my guest!
