  • large 2d dft from small 2d dft

    From Edward Montague@21:1/5 to All on Mon Jun 14 16:13:12 2021
    You may of heard about the recent avalanche in the Himalayas .

    Large scale 2D DFTs can help predict such calamities by finding areas where lanslides have occured.

    These large 2D DFTs are best computed using smaller 2D DFTs.

    Does anyone, within this group, have an explanation as to how this is done.
