Figure Lengend Snippet: (a) A low-resolution image; (b) The super-resolution image using bicubic interpolation method (note the blur effect); (c) The super-resolution image by nearest-neighbor interpolation method (note the jaggy effect on the edges); The upscaling factor is 4.

Article Snippet: Down-sampling operators D , associating with step 3a and step 3c in , are done by bicubic interpolation (In Matlab function: “imresize”). can be applied on the whole image or patch by patch.

Figure Lengend Snippet: Compare the proposed algorithm with some state-of-the-art approaches: Bicubic interpolation, 07’TIP [59], 08’TOG [53], 10’TIP [71], 11’IPOL [27], 11’SIAM [26] and 14’TIP [65]. The upscaling factor is 3. No ground-truth high-resolution images are available for quantitative comparison. Color images are better visualized in the pdf file.
