O článku:
A new numerical method of image processing suitable for
is presented. This method allows us to study both small- and
large-scale coronal structures that remain invisible on original
images because of their very high dynamic range of the coronal
brightness. The method is based on the use of adaptive filters
inspired by human vision and the sensitivity of resulting images
is thus very close to that of the human eye during an eclipse. A
high precision alignment method for white-light corona images is
also discussed. The proposed method highly improves a widely used
unsharp masking method employing a radially blurred mask. The
results of these numerical image processing techniques are
illustrated by a series of images taken during eclipses of the
last decade. The method minimizes the risk of processing
artifacts.
