| 摘 要： | 在AitckenPCA算法的基础上建立了色彩表示的宽带多光谱空间,并定义了"累积空间覆盖率(CSCR)"来表征特定空间下光谱的重建的效率.该空间采用宽带光谱匹配方法,希望在降低多光谱图象采样、传输、处理和存储开销的同时使色彩的表示精度有大幅度的提高.实验结果表明,该空间能以很高的精度来表示原始光谱空间.

| Abstract: | It is developed a wide-band multi-spectral space for color representation with Aitken PCA algorithm.This novel mathematical space using the broad-band spectra matching method aims to improve the accuracy of color representation as well as to reduce costs for multi-spectral images' sampling, transferring, processing and storing. The results show that the space can present our experimental original spectral spaces with a high efficiency. |
