summaryMultiSpectral Filter Arrays (MSFAs) is a snapshot multispectral imaging technology. It extends the traditional color filters mosaic (CFA, Bayer-like) to an arbitrary number of channels for multispectral acquisition. MSFAs technology is believed to provide a compact, robust and affordable mean for fast multispectral or accurate color image/video acquisition. Although the concept and design is ultimately simple, there are serious technological difficulties to realize this type of sensor in practice. Through this speech, I will provide an explicit listing and analysis of the different aspects. This is related to an article that has been recently accepted for publication in Sensors. MSFAs, similarly to CFAs, require a demosaicing process to provide a complete image. I will emphasize demosaicing as a pre-processing step and relate this with the aspects discussed above. This is based on the work of Xingbo Wang who is doing his PhD thesis under the co-supervision of myself, P. Gouton and Jon Hardeberg. I will also open to applications with a study on background extraction from multispectral video based on preliminary investigations presented at OMNIVIS this year.
