Joint Method of Interference Suppression and Super-Resolution for Chinese Characters Image with Interference

Figure 6

Super-resolution experiment I on Chinese characters image with dark background after interference suppression. (a) One Chinese character in Figure 2(d). (b) Result by bicubic interpolation. (c)-(f) Results by super-resolution methods of classical neighbor embedding [6], sparse representation [1, 9], transformed self-exemplars [14], and ours, respectively. (e)-(k) Magnification display of part region of (b)-(f), respectively.
