Super-resolution Reconstruction for Sub-pixel Image with Fiber Bundle Coupling
Xue Bing-bin · Jisuanji gongcheng · 2012
As the image coupled by the adjacent layer fibers has a sub-pixel dislocation,a super-reconstruction algorithm based on image complementary information is proposed.It makes pixel-level registration by traditional phase correlation,and sub-pixel registration by multi-peak fitting.Four B-spline curves for ultimate interpolation are used to fuse the matched image with the reference image.Experimental results show that the proposed algorithm can effectively raise the spatial resolution with less complexity,and the reconstruction image owns better quality.
