In this paper, we propose an improving method of removing the blocking artifacts on images based on the theory of projections onto convex sets (POCS) in 3 to decrease the blocking effect.

本文基于文献[3]中的利用凸集投影(POCS)理论的去方块方法，提出一种改进方案来降低图像的方块效应。

Needleman's theory was that one could spare the stomach by selectively blocking the enzyme responsible for inflammation, COX-2 (cyclooxygenase-2), while avoiding the one involved in maintaining the stomach lining, COX-1.
