Abstract:

A novel algorithm based on sub-pixel motion for super-resolution reconstruction of images is proposed.In this algorithm,the 1-dimension statistical characteristic of the image is used twice.Firstly,the N frames of the image are divided into the motion field and the background field.Secondly,the motion-range of the pixels in the motion field is estimated. After the motion estimation an d motion compensation,N motion compe nsation im es afe
obtained. At last,the data fusion technology is adopted to reconstruct a super-resolution image in combination of the information in the background.The experimental results show that the proposed algorithm is simper and less complex.Th e perform ance of this algorithm is better than the traditional bilinear interpolation method in minimum mean square error,signal-to-noise ratio and power sign al-to-noise ratio.

Key words: super-resolution reconstruction, motion estimation, motion compensation, data fusion
