1. A single-instruction multiple-data (SIMD) computing system that facilitates acceleration of dense optical flow (DOF) determinations, the system comprising: an image handler of a SIMD computing system configured to obtain an image that is stored in a memory, wherein the image is formatted as a canonical discretized rectangular grid of pixels; a SIMD processor of the SIMD computing system, the SIMD processor being coupled to the memory, the SIMD processor being configured to produce DOF data of the image by: defining multiple SIMD windows of pixels of the image, wherein each window includes multiple pixels of the image and only a portion of the image; and performing a successive over-relaxation (SOR) operation simultaneously on each the pixels of each of the SIMD windows, wherein the SOR operation performed on each pixel of each window is performed without local dependencies within its own window; a reporter of the SIMD computing system configured to present the produced DOF data of the image.
