Terahertz spectra reconstructed using convolutional denoising autoencoder for identification of rice grains infested with Sitophilus oryzae at different growth stages

[Display omitted] •THz-TDS technology was used to identify rice grains infested with Sitophilus oryzae at different growth stages.•CDAE was developed to reconstruct preprocessed THz spectra for eliminating noise.•RFC model was constructed to analysis original and reconstructed THz spectra. Rice grai...
