摘要
提山了一种新的光流场计算方法：首先，在几何代数域内推导了光流约束方程的新形式；然后，在速度场平滑的基础上，通过求解关于初值问题的热传导方程求解光流场；最后，给出光流场的数值解和仿真结果。实验证明此方法是有效的。
In this paper, a new improvement of optical flow estimation in Geometric Algebra domain was presented. Firstly a new optical flow constraint equation in Geometric Algebra domain was got, and then optical flow could be got by heat conduction equation based on smoothness directly on velocity field. At last the numerical solution and experimental results were given. Experimental results showed that this method was suitable and effective.
