摘 要: 提出一种基于加权全变分与小波的联合修补图像的新偏微分方程模型,用于有噪图像的修补。该方法综合利用了全变分与小波的优点,同时应用加权全变分的方法,使之更具有适应性。实验表明:对有噪图像进行修补效果较好,可以很好地保持纹理及边缘,减少Gibbs现象。
关 键 词: 偏微分方程;加权全变分;小波;图像修补

Abstract: This paper studies a partial differential equation model which combines weighted total variation approach and wavelet approach to solve the image inpainting problem. This method combines advantages of total variation and wavelet transform. Moreover, using the method of weighted total variation makes it more adaptive. The experiment shows that the effect of inpainting is better which preserves the texture and reduces the Gibbs phenomenon.
Key words: partial differential equations; weighted total variation; wavelet; image inpainting
