CUDA Resampling Script

This script resamples volumes in SimpleITK-readable formats using the CUDA-based B-Spline interpolation algorithm from this repository.

Requirements

• Python 3
• SimpleITK
• CUDA (tested on 10 and 11)

Building

• Set the CUDA_PATH environment variable to point to CUDA (e.g. /usr/local/cuda-11.0.3 or /opt/cuda/)
• Open a terminal in the git directory and run ./build.sh
• Alternatively, manually run the commands in build.sh
• You should end up with the libcudaresize.so library in the current directory

Installation

• Copy the libcudaresize.so file to /usr/lib or another path on LD_LIBRARY_PATH
• Copy the cudaresize.py file somewhere convenient

A Note on CUDA

Compiling against CUDA 11 gives a number of deprecation warnings; these are in the underlying CubicInterpolationCUDA repository (written for CUDA 3 and last updated for CUDA 5).
