Today I read a paper titled “L2-optimal image interpolation and its applications to medical imaging”
The abstract is:
Digital medical images are always displayed scaled to fit particular view.
Interpolation is responsible for this scaling, and if not done properly, can significantly degrade diagnostic image quality.
However, theoretically-optimal interpolation algorithms may also be the most time-consuming and impractical.
We propose a new approach, adapted to the needs of digital medical imaging, to combine high interpolation speed and superior L2-optimal image quality.
