SimpleCT is a simple contour tree library with MATLAB interface.
If you use this code in your work please cite the following publication:

DESCRIPTION:
SimpleCT simply computes the contour tree of 2D/3D images and does heuristic pruning.
Contour tree computation algorithm is based on the paper:
H. Carr, J. Snoeyink, and U. Axen. Computing contour trees in all dimensions. In Proceedings of the eleventh annual symposium on Discrete algorithms, pages 918–926, San Francisco, California, United States, 2000. Society for Industrial and Applied Mathematic.
This implementation uses OpenMP for multicore processing. With this, join and split trees are computed in parallel. Although, it is not required, it is strongly recommended to install OpenMP and link the libraries for faster computation.
