Combining the genetic algorithm and successive projection algorithm for the selection of feature wavelengths to evaluate exudative characteristics in frozen–thawed fish muscle

•Hyperspectral imaging was used to predict drip loss in frozen–thawed fish.•Five key wavelengths were selected by combination of GA and SPA.•GA–SPA–LS-SVM and GA–SPA–MLR models showed satisfactory performances.•The distribution maps of drip loss were generated. The potential use of feature wavelengt...
