Paper

This code implements "Interactive GPU active contours for segmenting inhomogeneous objects". Please cite if you find it useful. https://link.springer.com/article/10.1007/s11554-017-0740-1

Common Mistakes

• Make sure kernels directory is next to the compiled binary
• If on linux, make sure "glxgears" works
• Make sure your drivers are up to date

Readme

• Compile using CMake
• Typical usage scenario:

./IGAC -p nvidia -i data/noiseTumour3D.tif
