摘要: 提出轮廓波域MRF样本修补方法,通过轮廓波变换把待修补图像进行多尺度、多方向修补。实验结果表明,与传统的离散小波修补方法相比,轮廓波域MRF样本修补技术能更好抑制马赛克现象,保持良好的纹理和结构特征。

Abstract: An MRF-based exemplar inpainting technology??in the contourlet domain is diccussed. The image is converted to contourlet domain by contourlet transform and is inpainted according to  multi-scale and multi-direction. Compared with the classical discrete wavelet domain inpainting algorithm, the proposed method can more further suprress mosaic effect and preserve the textural and structural feature better.

Key words: Markov Random Field(MRF)-based exemplar inpainting, discrete wavelet transform, contourlet transform
