Parallel computations by GPU for displacement vectors fields construction

The paper presents the recursive-search based algorithm f determining the displacements of surface patch (optical flow) to be applied on GPU utilizing the parallel computations principle. OpenCL computing language is used to implement the parallel computations algorithm which is focused on application on AMD Radeon GPUs. The results of testing of the proposed algorithm show the multiple decreases the time of displacement vector field construction while maintaining the accuracy and robustness.
