Abstract
Multispectral reflectance imaging is a non-destructive analysis technique that can be used to investigate the micro appearance of complex surface materials that show striking angle-dependent colour effects. Basic analysis of multispectral goniometric measures includes the extraction of components of the bi-directional reflectance distribution function (BRDF) and visualization in different colour spaces for human classification tasks. Other mathematical procedures include pattern matching for recognition and classification of spatially-varying reflectance properties and the investigation on the statistical organization of colour coordinates from user-defined regions of interest. In the present talk, I will focus on the research I have conducted in the last years on certain structurally coloured biological materials found in nature and synthetic surface coatings containing special flake-shaped pigments.
Series This talk is part of the Probabilistic Systems, Information, and Inference Group Seminars series.
