Nondestructive Detection of Egg Freshness Based on Infrared Thermal Imaging.In this paper, we proposed a nondestructive detection method for egg freshness based on infrared thermal imaging technology.  We studied the relationship between egg thermal infrared images (different shell colors and cleanliness levels) and egg freshness under heating conditions.  The relationship between the thermal infrared images of eggs after thermal excitation and egg freshness was further studied.  Finally, we introduced SegNet neural network image segmentation technology to segment the egg thermal infrared images.  The results also showed that infrared thermography combined with deep learning algorithms could detect egg freshness with an accuracy of over 94%, providing a new method and technical basis for online detection of egg freshness on industrial assembly lines.
