How to draw the picture of Fig(b) and Fig(c) in your ECCV2022 paper?

How to draw the DCT-based spectral maps of Fig 1(b) and Amplitude-Frequency curves of Fig(c) in your ECCV2022 paper?

Thank you very much!

After obtaining the HR images by your model, you can transmit the images into the DCT domain by cv2.dct.
Then, you will get the spectral maps and you can visualize them and draw the figures.
