title: Spectral reflectivity recovery from the tristimulus values using a hybrid method.
abstract: This study proposes an effective and accurate mechanism for spectral reflectivity recovery based on a hybrid technique. Adaptive non-negative matrix transformation, three-dimensional interpolation, and two-dimensional interpolation were reconstructed to an integrative hybrid recovery method. The existing spectral reflectivity data of 1269 Munsell matte color chips were used as reference data. Under the standard condition of a D65 illuminant and a 10° observer of 1964 CIE, the spectral reflectivity of the 1269 Munsell colors was reconstructed successfully using the optimized hybrid recovery method. The root mean square error and goodness of fitting were used to determine the quality of the presented method. Using the hybrid method, the strategy for fast and reliable spectral reflectivity recovery of given images were also presented and demonstrated.
