Special thanks to Armaggheddon97 and his 4090

This repository hosts a finetuned [Ultralytics](https://www.ultralytics.com/) [YOLOv8s](https://github.com/ultralytics/ultralytics) model specifically designed for **barcode and QR code classification and detection**. Building upon the robust and efficient architecture of YOLOv8, this model has been fine-tuned on a comprehensive dataset of over 5,000 images, encompassing various barcode types (EAN13, Code128, etc.) and QR codes. YOLOv8 is renowned for its speed, accuracy, and ease of use, making it an excellent foundation for specialized object detection tasks like barcode and QR code recognition. This finetuned model aims to provide a reliable and performant solution for applications requiring automated barcode and QR code scanning and identification. We hope this model proves useful for your projects! For general YOLOv8 documentation, please refer to the Ultralytics Docs. For specific questions or discussions related to this finetuned model, please raise an issue on its [Hugging Face model page](https://huggingface.co/Piero2411/YOLOV8s_Barcode_Detection). ##

Usage

### CLI You can use this model directly from the Command Line Interface (CLI) using the `yolo` command. Make sure the `YOLOV8s_Barcode_Detection.pt` model file is accessible in your current directory or specified with its full path. ```bash yolo predict model=YOLOV8s_Barcode_Detection.pt source='path/to/your/image.jpg' ``` The `yolo` command offers various modes and arguments (e.g., `imgsz=640`). For more details, consult the YOLOv8 [CLI Docs](https://docs.ultralytics.com/usage/cli/). ### Python This model can also be easily integrated into your Python applications. The usage mirrors the standard Ultralytics YOLO API. ```python from ultralytics import YOLO # Load your finetuned model model = YOLO("YOLOV8s_Barcode_Detection.pt") # Perform object detection on an image results = model("path/to/image.jpg") # Optionally, visualize the results results[0].show() # You can also export the model to other formats (e.g., ONNX) # This is useful for deployment in various environments. # path = model.export(format="onnx") # uncomment to export ``` For more advanced Python usage, including training, validation, and different prediction modes, refer to the YOLOv8 [Python Docs](https://docs.ultralytics.com/usage/python/).

Model Details

This specific model, `YOLOV8s_Barcode_Detection.pt`, is a finetuned instance of the **YOLOv8s (small) detection model**. It has been specifically trained for **barcode and QR code classification and detection**. ### Dataset The model was finetuned on a custom dataset comprising **over 5,000 images**. This dataset includes a wide variety of barcode types such as EAN13, Code128, and many more, alongside various QR code instances, ensuring robustness across different real-world scenarios. ### Training Parameters The training process leveraged a pre-trained `yolov8s.pt` checkpoint and was conducted with the following key parameters: ```python # Base model used for finetuning model = YOLO('yolov8s.pt') # Training parameters results = model.train( data='dataset/data_autosplit.yaml', # Path to the custom dataset epochs=30, # Number of training epochs patience=10, # Early stopping patience batch=16, # Batch size (adjust based on GPU memory) imgsz=640, # Image size for training name='yolov8_large_dataset_v1', # Run name # Augmentation parameters degrees=180, # Random rotation (0-180 degrees) translate=0.1, # Image translation (0-1) scale=0.5, # Image scaling (0-1) shear=10, # Image shearing (degrees) perspective=0.001, # Image perspective (0-0.001) fliplr=0.5, # Horizontal flip (probability) flipud=0.5, # Vertical flip (probability) cutmix=0.2, # CutMix augmentation (probability) ) ``` The combination of a robust base model, a diverse custom dataset, and carefully selected training parameters aims to provide high accuracy and generalization for barcode and QR code detection across various real-world scenarios.
