将切向量的零散度条件与TV-norm相结合,利用能量极小化方法得到非线性的TV-Stokes方程,对切向量进行修正,并根据修正后的切向量来重构图像,提出了一种基于TV-Stokes方程的图像去噪算法,最后通过仿真实验验证了本算法的可行性和有效性。
This work combines the zero divergence condition on the tangential field with TV-norm and uses an energy minimization method to obtain a nonlinear TVStokes equation,which is used to smooth the tangential vectors of the noising image,reconstruct the image to fit the smoothed tangential vectors,and then propose an algorithm based on TV-Stokes equation for image denoising.Finally,the validity and the feasibility of this algorithm have been tested on real images.
