Comparison of the experimental time complexity of the proposed algorithm and previous region growing method. Shown are the values of the simulation time for phantoms at different voxel sizes. Times are normalized by the average time achieved for 200 μm region growing phantoms. Power law regression trend lines are displayed in solid (the proposed octree algorithm) and dashed (the region growing method).
