Weighted Curvature-preserving PDE Based Image Regularization Method
加权型曲率保持 PDE 图像滤波方法

A weighted curvature-preserving partial different equation (PDE) based filtering method is proposed. First, it is pointed out that the tensor-driven curvature-preserving PDE filtering methods can not preserve image edge very well because that the methods does not take into account the differences between integral curves. Then, we employ local image directional information to design weight coefficients for different integral curves, and present a new tensor-driven curvature-preserving PDE. Experimental results indicate that new method shows superior performance on preserving image edge and curvature geometric structure, as well as some image enhancement ability.
