Polyvinyl alcohol (PVA), polyvinyl butyral (PV and poly-N-vinylpyrrolidone (PNVP) were used to trap the alcohols and acids during a kiwifruit ripening period. This research proved that discrimination of differences is feasible from an unripe stage to a ripe stage and from a ripe stage to an over-ripe stage.Facial expression recognition (FER) in the wild received broad concerns in which occlusion and pose variation are two key issues.
