The goal of the annotation is to provide ground-truth labels that will be used to predict the label of unseen logos. It is extremely important to provided quality annotations, otherwise the predictions won't be qualitative.

'''It is extremely important to provide quality annotations, otherwise the predictions won't be qualitative'''.
   −
The ''value'' field should only be completed for "brand" and "label" types. The value should match one item in the associated taxonomy, otherwise it won't be used for prediction. The field value is lowercased before saving the annotation.

If you're not sure of how you should annotate a logo, ask on the Slack, in the #ai-logo-detection channel.
 +
 
 +
== How to? ==
 +
1. Open web interface: https://hunger.openfoodfacts.org/logos
 +
 
 +
2. Select logos to be annotated (click each desired logo with your mouse)
 +
 
 +
3. Fill ''value'' and ''type'' corresponding to the selected logos. Be sure to '''check that the ''value'' and ''type'' are correct before submitting the annotation''' :
 +
* The ''value'' field should only be completed for "brand" and "label" types.
 +
* The value should match one item in the associated taxonomy, otherwise it won't be used for prediction. The field value is lowercased before saving the annotation.
 +
* Use ''QR code'' type for QR codes, ''Packager code'' for packager codes (code surrounded by a circle), ''Brand'' for brand logos and ''Label'' for label logos.

If more than one logo is visible on the crop, do not annotate it. A flag system should be available in the future to report them.

If the logo is truncated, annotate it anyway if it can still be recognized.
    
You can click on the blue link on the top-right corner of each logo card. It will open a new tab with this specific logo as reference. It's really useful to find similar logos to annotate.
