Research on Hyperspectral Modeling of Total Iron Content in Soil Applying LSSVR and CNN Based on Shannon Entropy Wavelet Packet Transform
The influence of some seemingly anomalous samples on modeling is often ignored in the quantitative prediction of soil composition modeling with hyperspectral data.Soil spectral transformation based on wavelet packet technology only performs pruning and threshold filtering based on experience.The feature bands selected by the Pearson correlation coe
