We can do it better, in archaeomagnetism

The relocation of geomagnetic data across distances of hundreds of kilometers and assuming a dipolar geomagnetic field is a common practice in archaeomagnetism. The errors due to this practice are rarely taken into account. This work analyses the time and space distribution of these...

Restoration of noisy images

If there is noise, we can’t understand what we hear. In the same way, a noisy image can make it very difficult for us to recognise what we are seeing. Fortunately, techniques exist to restore noisy images so that they can be seen perfectly clearly. In this article a new restoration technique is...
