The Fourier transform, which splits a complicated signal into individual pure frequencies, was devised over 200 years ago but only became widely used after the development of an algorithm called the ...

Recent advances in triangular grid algorithms have revitalised the field of image processing by offering robust alternatives to the conventional square sampling schemes. These approaches utilise the ...

Perfusion CT scanning, an emerging imaging technology, got a bad rap last year when a machine set to incorrect radiation levels overdosed hundreds of people in Los Angeles. In the wake of this ...

Take a hammer to a mirror and you will fracture the image it produces as well as the glass. Keep smashing and the image becomes more broken. When the pieces of glass are the size of glitter, the ...

Unmanned aerial vehicles (UAVs) paired with artificial intelligence image processing can provide data that helps researchers evaluate the health and conservation status of Australia’s koala population ...

In the wake of recent radiation overdoses, researchers excited by CT perfusion's promise for diagnosing stroke, cancer, and possibly heart disease have developed a way to reduce the amount of ...
