The study on soil spectral reflectance features is the physical basis for soil remote sensing. Soil organic matter content influences the soil spectral reflectance dramatically. This paper studied the...
基于EMD的土壤有机质含量近红外光谱检测（Near-infrared Spectrum Detection of Soil Organic Matter Content Based on Empirical Mode Decomposition）
土壤有机质 检测 经验模态分解 近红外光谱
2010/12/29
以检测土壤有机质含量为例，探讨经验模态分解在土壤近红外光谱检测中的应用，提出了应用的原理和步骤。用处理后的光谱计算了土壤中的有机质含量，并与九点平滑和小波变换方法的处理结果进行了对比分析。结果表明：与传统的九点平滑处理结果相比，SNR从3 dB左右提高到10 dB左右，原始信号与消噪信号之间的标准差由2.972降到0.901；预测集的决定系数r2由0.9410提高到0.9803, 预测均方根...
