This repository hosts a finetuned Ultralytics YOLOv8s 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 <a href="https://docs.ultralytics.com/">Docs</a>. For specific questions or discussions related to this finetuned model, please raise an issue on its Hugging Face model page.

<details open> <summary>Usage</summary>

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.

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.

<div align="center">Model Details</div>

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.
