Research of a data preprocessing method for near infrared spectrum of coal
For noise existed in original near infrared spectral data of coal, a data preprocessing method for near infrared spectrum of coal was proposed based on De-SNV and wavelet threshold denoising. Spectrum data processed by Savitzky-Golay smoothing and De-SNV was further processed by default soft thresho...
