Abstract:
A modification of Horn and Schunk’s approach is investigated, which leads to a better preservation of flow discontinuities. It improves Horn–Schunk model in three aspects: (1) It replaces the smooth weight coefficient in the energy equation by the variable weight coefficient. (2) It adopts a novel method to compute the mean velocity. The novel method also reflects the effect of the intensity difference on the image velocity diffusion. (3) It introduces a more efficient iterative method than the Gauss–Seidel method to solve the associated Euler–Lagrange equation. The experiment results validate the better effect of the improved method on preserving discontinuities.
