A Method for Noise Removal Based on Fourth-Order Partial Differential Equations
Fa Wang · Microcomputer Development · 2003
Demonstrate a method for noise removal based on fourth-order partial differential equations(PDE). Approximating image with a piecewise planar image can remove noises while preserving edges well and avoiding blocky effects which is easily seen in images processed by second order PDE. The application result indicates this method is efficient.
