目的 提出一种全变分(TV)修补模型的改进方案,而且具有良好的边缘特性,并弥补原有的TV修补模型的不能满足连通性原则的缺陷.方法 定义在图像修补区定义一种"加权全变分,即沿修补区边界法线方向的梯度分量对全变分的贡献,远大于沿切线方向的梯度分量的贡献.结果 通过对相同的受损图像,采用原有模型和改进模型作比对实验表明,文中的改进模型可以完全满足图像修补的连通性原则.结论 改进的TV模型较原始TV模型更适合于非纹理图像修复.
目的 提齣一種全變分(TV)脩補模型的改進方案,而且具有良好的邊緣特性,併瀰補原有的TV脩補模型的不能滿足連通性原則的缺陷.方法 定義在圖像脩補區定義一種"加權全變分,即沿脩補區邊界法線方嚮的梯度分量對全變分的貢獻,遠大于沿切線方嚮的梯度分量的貢獻.結果 通過對相同的受損圖像,採用原有模型和改進模型作比對實驗錶明,文中的改進模型可以完全滿足圖像脩補的連通性原則.結論 改進的TV模型較原始TV模型更適閤于非紋理圖像脩複.

Aim To propose an improved TV inpainting model. The improved one has favorable marginal property in order to make up the limitation of the TV inpainting model which can not meet the connection principle. Methods A weighted total variation is defined in the inpainting domain, which means the contribution of gradient along the tangent direction of the inpainting domain is siginificantly larger than that of the gradient along the norm direction. Results The experiments which compare the results of adopting the original and improved model to the same damaged Image show that the improved model can meet the connection principle. Conclusion The improved model is more suitable to the non _ texture image inpainting.
