Hi everyone!
If you work with texture analysis (medical imaging, satellite data, or industrial defect detection), you've likely noticed that classic libraries like mahotas and scikit-image compute Gray-Level Co-occurrence Matrices (GLCM) and Haralick features strictly on the CPU. On large datasets, this quickly becomes a major pipeline bottleneck.
To solve this, I wrote and open-sourced haralickt — a library that offloads these computations to the GPU using vectorized matrix operations in PyTorch and CUDA.
Key highlights:
• > 20x faster than traditional CPU implementations on high-resolution images and batches.
• Identical numerical precision to classic implementations (verified against mahotas).
• PyTorch-native: works seamlessly with torch.Tensor on GPU without costly CPU-GPU data transfers.
• Open Source (MPL 2.0): free to use in research and commercial projects.
Quick installation:
bash
pip install haralickt
Используйте код с осторожностью.

This is my first public release (v1.0.0), so I would really appreciate any feedback, bug reports, or ideas for new features. If you find it useful for your projects, a star on GitHub would mean a lot!
