Embodiment 1
[0079] combine Image 6 , Figure 7 and Figure 8 , for the three pictures "foreman", "comic" and "baby", the super-resolution reconstruction process is performed on the three pictures "foreman", "comic" and "baby" through the sparse representation single-frame image super-resolution reconstruction algorithm based on the separation of the main structure, and the magnification factor is 2 times. Details of peak-to-noise ratio and running time for raw high-resolution images, compared to other novel algorithms.
[0080] Table 1-1 Comparison of signal-to-noise ratio (PSNR) and running time of pictures "foreman", "comic" and "baby" enlarged by 2 times

[0082] combine Figure 2-Figure 5 ,from figure 2 and image 3 It can be seen that using the proposed adaptive dictionary size can reconstruct better high-resolution images than other dictionary sizes, and it is well adapted to the characteristics of different images.
[0083] from Figure 4 and Figure 5 It can be...
