摘要: Soybeans are used for human consumption or animal feed due to their abundant protein content. In this study, visible-near infrared (VNIR) hyperspectral imaging (HSI) and short-wave infrared HSI combined with three-levels data fusion methods were employed to detect the protein content of soybean seeds, including measurement-level fusion, feature-level fusion, and decision-level fusion. Additionally, three novel decision-level fusion methods were proposed, including binary linear regression, feature-based multiple linear regression (MLR), and model-based MLR. An IVISSA-SPA-MLR model based on decision-level fusion demonstrated the best predictive performance, with a residual prediction deviation value of 3.6796. The results suggested that the IVISSA-SPA-MLR achieved accurate predictions, effectively enabling precise detection of soybean seeds protein content. Decision-level fusion proved to be an accurate and efficient quantitative detection technique, enhancing the predictive performance of regression models. This research provides a novel method for protein content detection in food products and introduces new strategies for data fusion.
