Filter array based spectral imaging : Demosaicking and design considerations
Wang, Xingbo (Doctoral thesis at NTNU;2016;, Doctoral thesis, 2016)Spectral imaging apparatus in current use are often cumbersome, costly and slow in operation, which becomes a major obstacle to extensive use of spectral imaging in several application areas. In recent years, the technical ... -
Multispectral filter arrays: Recent advances and practical implementation
Lapray, Pierre-Jean; Wang, Xingbo; Thomas, Jean-Baptiste; Gouton, Pierre (Journal article; Peer reviewed, 2014)Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the ... -
Multispectral imaging: narrow or wide band filters?
Wang, Xingbo; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Gouton, Pierre (Journal article; Peer reviewed, 2014)In every aspect, spectral characteristics of filters play an important role in an image acquisition system. For a colorimetric system, traditionally, it is believed that narrow-band filters give rise to higher accuracy ...
