We’re excited to announce ITK 5.4.7, the cross-platform, open-source toolkit for N-dimensional scientific image analysis!

🔥 Highlights

🐍 ITK Python packages now use the Pool thread backend by default, better tuned for most workloads. TBB remains available.

🧭 NRRD IO now supports 5D datasets, including time sequences of 3D vector, velocity, and color images.

🖼️ TIFF IO adds signed and unsigned 32-bit integer support for 2D images and multi-page volumes.

⚡ Diffusion tensor reconstruction is substantially faster by computing its constant tensor-basis SVD once instead of once per voxel.

🛠️ Single-precision FFTW builds, GDCM/DCMTK integration, CI caching, CastXML wrapping, and C17/C23 support are more robust.

🤝 Community Thanks

Big cheers to Andras Lasso, Bradley Lowekamp, Csaba Pinter, Hans Johnson, James Butler, and the entire ITK community! 🙏🎈

📈 What’s Next?
The ITK 6 Release Candidate is coming, with modernized C++, Python wrapping, and toolkit architecture.

Download ITK 5.4.7 and supercharge your image analysis! 🏁
