...Rumpf and Strzodka (2001) presented a GPU implementation as early as in 2001. Updating the level set function / for voxels far away from the contour, does not significantly affect the movement of the contour. This observation has lead to two different optimization techniques, known as narrow band and sparse field. Both reduce the number of voxels updated in each iteration. The narrow band method updates / only within a thin band around the contour. However, the sparse field method updates / only at the neighbor pixels of the contour. Although these methods reduce the number of threads considerably, they introduce branch divergence. All of these level set methods also require global synchronization after each iteration. Hong and Wang (2004) used shader programming to create a GPU implementation of level sets for 2D images, and reported a speedup of over 10 times that of a CPU implementation....
