1. A parallel-processing computing system that facilitates acceleration of dense optical flow (DOF) determinations, the system comprising: an image handler configured to obtain an image that is stored in a memory; an initializer configured to obtain a thread count (T) and a total number of iterations (n) for convergence of an iterative dense optical flow (DOF) operation performed on the obtained image, the initializer being further configured to determine a number of iterations per thread (IPT) based upon the thread count and the total number of iterations; and a parallel processor configured to simultaneously execute multiple threads, each thread performing the iterative converging DOF operation on pixels of the obtained image, the parallel processor being further configured to repeat the simultaneous execution of the multiple threads a number of times matching the determined IPT number to produce DOF data of the image, wherein the simultaneous execution of the multiple threads is performed in accordance with an execution of a successive over-relaxation (SOR) operation performed simultaneously on each of the pixels included within a plurality of windows that are defined within the image, and wherein the SOR operation is performed on each of the pixels within each window from among the plurality of windows without local dependencies within its own respective window.
