图像插值放大:不改变原始图像的像素值,只是内插出“亚像素”位置上的像素点。
典型论文:
[1] X. Li and M. T. Orchard. New edge-directed interpolation. Image Processing, IEEE Transactions on, 10(10):1521–1527, 2001. NEDI
[2] L. Zhang and X. Wu. An edge-guided image interpolation algorithm via directional filtering and data fusion. IEEE Transactions on Image Processing, 15(8):2226, 2006. DFDF
[3] X. Zhang and X. Wu. Image interpolation by adaptive 2-d autoregressive modeling and soft-decision estimation. IEEE Transactions on Image Processing, 17(6):887–896, 2008.
[4] S.Mallat and G.Yu, Super-Resolution with Sparse Mixing Estimators, submitted to IEEE Trans. on Image Processing, 2009.
这4篇论文,是最有代表性的。 当然Mallat做的超分辨重建,从实现结果而言,本质上是图像内插。
