Abstract
A novel method based on digital images in time domain combined with convolutional neural network (CNN) is proposed for discrimination and analysis of the adulterated mutton. For this, 195 sample images during the constant temperature heating process (about 10 min) were combined with CNN for qualitative discrimination and quantitative prediction of adulterated mutton. Furthermore, the hypothesis that temperature disturbance can improve the detection ability of adulterated mutton was confirmed by comparing the model performance of the initial heating stage and the entire heating process. The experimental results show that the performance of the latter was superior to that of the former. The accuracy of the qualitative discriminant model was increased by 7.33%, the R and RPD of the quantitative prediction model of the duck/pork in adulterated mutton were increased by 0.08/0.07 and 0.85/0.87 respectively, while the RMSE decreased by 0.01/0.01. Consequently, the proposed method can be used for detecting adulterated mutton effectively and accurately.
