| 摘 要： | 提出了一种在马尔科夫网络框架下基于样本块的图像超分辨率算法。算法根据相似性选取多个样本块作为图像重建的候选,在候选集中计算图像块先验概率和图像块之间的相容性,最后在马尔科夫框架下选取最优图像块,合成最终的高分辨率图像。实验证明本文提出的算法具有较好的超分辨率效果。

| Abstract: | A new method for image super resolution based on example and Markov Network is introduced in this paper.The method proposed first uses similarity to select several image patches as candidates for image reconstruction,compute the prior of the patches and the compatibility among neighbor patches.Then choose the most suitable patch in Markov Network for final high resolution image reconstruction.Experiments show that the method is effective. |
