英文摘要 | This paper proposed a super-resolution method based on neighborhood regression of internal examples, in order to improve the resolution of medical images. First, it treated the input low-resolution image as a high-resolution image to construct an internal image training set based on its own instance, no longer dependent on the external training set. Then, it divided the high-resolution reconstruction into high-frequency reconstruction and low-frequency reconstruction, neighborhood regression method reconstructed the high-frequency detail part of the image, and bicubic interpolation method reconstructed the low-frequency part. Finally, iterative combination method combined the high-frequency component and the low-frequency component to get a high-resolution image of the final output. The experimental results show that the proposed method outperforms the traditional super-resolution reconstruction algorithm, and the reconstructed medical image visual effect is more realistic. |
