(A) Tree-structured parallel summation algorithm. The sums between every two pixels within the same block are computed in synchronization, and repeated until the final result is obtained. (B) Dividing and distributing subsets of the data on multiple GPUs for search and refinement. (C) Dividing and distributing subsets of the data on multiple GPUs for 3D reconstruction.
