Abstract:
The investigation focuses on development of colour information transformation
model which takes into account different importance of different domains of colour
space depending on the aim of the colour reproduction process and types of print
production. The methods of creating the multidimensional colour look-up tables
of colour imaging devices are proposed. Namely, the method for direct mapping
device-dependent colour space to device-independent based on spline
approximation of the data from original test chart taking into account the local
non-uniformities in the colour space and criterion of the transformation accuracy.
This method reduced the errors during reproduction memorable colours and
important for scene colours. We also proposed a combined method of reverse
mapping device-independent colour space to device-dependent device signals
taking into account the decomposition of the space on the priority area of colour reproduction. Both these methods allow reducing error during the process of
transformation of colour coordinates of images within the reproduction process.
