To enhance the efficiency of banana quality management, an automated freshness grading system based on real-time image processing was developed. The system integrates a camera for image acquisition and employs portable edge devices (Nvidia Jetson Orin NX or Jetson TX2) to classify banana freshness into four levels, displaying results along with confidence scores in real-time. A lightweight YOLO-based banana freshness detection method (YOLO-BFD), built on the YOLOv7-tiny framework, was designed to enable high-accuracy, real-time processing on ed...
