A novel data enhancement method for olfactory visual images was proposed in this study, combined with deep learning to achieve the accurate prediction of total volatile basic nitrogen (TVB-N) content in chilled mutton. Specifically, the sliding-window was defined and used to separately extract different regions of interest from each sensing region by encoding and decoding the sliding position information, so the olfactory visual image was enhanced. This enhancement method considered the position shift and uneven colour presentation of sensitive points during the preparation and reaction of olfactory visualization sensor array.

Taking ofloxacin (OFX) residues in mutton as an example, the near-infrared hyperspectral imaging combined with explainable AI was used to evaluate the importance of feature wavelengths in the convolutional neural network-stacked sparse auto-encoder (CNN-SSAE) model for chemical properties.

Objectives: The feasibility of short-wave infrared hyperspectral imaging (SWIR-HSI) in detecting the contamination status and species of (EC), (SA) and (ST) contaminated on mutton was explored.
Materials And Methods: The hyperspectral images of uncontaminated and contaminated mutton samples with different concentrations (10, 10, 10, 10, 10, 10 and 10 CFU/mL) of EC, SA and ST were acquired.
