摘要：
A procedure for spectral recovery method based on color constancy is proposed from camera response values. The proposed method standardizes camera response values under different light sources by using different color constancy algorithms, and applied the pseudo inverse operation with the camera responses expansion to achieve the spectral reflectance recovery. To reduce the influence of external light source, the crossover combination of light sources and color constancy algorithms are calculated to determine the optimal selection of processing. The effectiveness of the color constancy algorithm was verified by using the spectral accuracy comparison and image similarity. The experimental results show that color constancy can significantly improve the spectral recovery accuracy, and the grey edge has the best performance.
