LR image #4

It uses FFT and IFFT. |
The super-resolution scale in this article is in three dimensions or two dimensions. Can the Fourier transform reduce the resolution simultaneously in three dimensions |
Yes, it can reduce in 3 dimensions. I've implemented it. |
Can you show me this part of the code? Many of the documents I have seen are only degrading the resolution by zeroing the outer part of the 3D k-space along two axes representing two MR phase encoding directions. |
Here. Let me know if there is a better method. |
I looked at your method and it seems to be truncated in both phase encoding directions. |
zeroing the outer part of the 3D k-space along two axes representing two MR phase encoding directions, then inverse Fourier transform will be better. The resulting image will be the same size as the hr image |
How do low-resolution images are simulated from high-resolution images? Is it using cubic interpolation?
