Sammendrag
In this paper we present and discuss our recent research using three approaches for fast and
cost-effective acquisition of multispectral colour images; using a stereoscopic camera with
additional optical filters, using an extension of the traditional colour filter array beyond the
conventional three channels, and using active LED illumination in conjunction with RGB
or panchromatic area image sensors. An important goal for this work is to achieve faster
and more practical solutions for multispectral colour imaging, paving the way for new
application areas and more widespread use, beyond the scope of the resarch laboratories.
