摘要
将求解二次椭圆偏微分方程问题的多格网算法应用到卫星影像的恢复中。其基本思想是在将由总变分求极小生成的偏微分方程离散成为差分方程的过程中,采用不同大小的格网。在取得较好恢复结果的同时,提高了传统图像恢复算法的运算效率,降低了恢复运算所需要的时间。
Multi-grid algorithm to solve the elliptical part differential equation is applied on the ocean satellite image restoration. The basic idea is to adopt different grids during the process of discretizing the equation obtained by the total variation minimization into difference equation. The computation efficiency of the existing algorithm is improved with lower computation time, at the same time, good restoration results are obtained.
