Local and Contextual Controlled Fourth Order Partial Differential Equations for Noise Removal
2012
Procedia Engineering
In this paper, we propose a local and contextual controlled (LCC) fourth order PDE method for noise removal. In our method, two discontinuity measures are incorporated into a LCC fourth order PDE, where the joint use of the two discontinuity measures leads to a complementary effect for edge preservation. Moreover, the proposed method inherits the advantage of fourth order PDE which is able to avoid the blocky effects widely seen in images processed by second order PDE. Compared with existing
