| 1. | Second , a novel algorithm named model predicition ( mp ) is proposed to wipe off spectral correlations of hyperspectral images . mp algorithm finds the linear model of hyperspectral images , in which predictive coefficients are set up that is based on snr . because predictive coefficients include current spectral band , average entropy of the error data is decreased and snr is increased after mp Mp算法建立了高光谱图像的线性模型,推导出了信噪比意义下的最佳预测系数,由于系数中包含了当前谱带的数据,因此经过mp算法去相关之后,残差图像的平均熵有所降低,同时信噪比提高很多。 |
