Open Food Facts Nutriscore detection dataset

This dataset was used to train the Nutri-score object detection model running in production at Open Food Facts.

Images were collected from the Open Food Facts database and labeled manually. Just like the original images, the images in this dataset are licensed under the Creative Commons Attribution Share Alike license (CC-BY-SA 3.0).

Fields

• image_id: Unique identifier for the image, generated from the barcode and the image number.
• image: Image data.
• width: Image original width in pixels.
• height: Image original height in pixels.
• meta: Additional metadata.
  • barcode: Product barcode.
  • off_image_id: Open Food Facts image number.
  • image_url: URL to the image on the Open Food Facts website.
• objects: Object detection annotations.
  • bbox: List of bounding boxes in the format (y_min, x_min, y_max, x_max). Coordinates are normalized between 0 and 1, using the top-left corner as the origin.
  • category_id: List of category IDs.
  • category_name: List of category names.

Versions

• 1.0: Original data used to train the tf-nutriscore-1.0 model.
• 2.0: New version of the dataset with improvements over the original version: the bounding boxes are more tightly cropped around the Nutri-score, some labeling errors were corrected, and images for which the model was failing were added to the dataset to improve future versions of the model.
