Abstract:
This paper presents a unique spectral modelling approach suitable for digital camera image processing. The proposed vector model combines both the magnitude and directional characteristics of the vectorial RGB color inputs and enforces orientation constraints in an orthogonal color system to produce outputs which can simultaneously match luminance and chrominance characteristics of the captured image. Thus, the model enhances the performance of commonly used practical demosaicking solutions. Moreover, spectral models previously used in demosaicking can be seen as special cases of the proposed vector model
