Introduced in 2019, Facial Recognition in Canto has been improving ever since. Based on Amazon Rekognition technology, this technology matches faces “based on their visual geometry, including the relationship between the eyes, nose, brow, mouth, and other facial features”.
In Canto, due to privacy concerns of some organisations, your Canto account manager needs to request this feature turned on (please contact databasics). Next, your Canto admin needs to enable this feature in Settings. To set up Facial Recognition in Settings, go to Configuration Options – Recognition. Here you will have to select different options:
- Confidence Level (0-100%)
The Amazon Rekognition uses what is called “probabilistic system”, where determinations cannot be made with absolute precise accuracy, it is instead, a prediction. Thus, when setting the Confidence Level, you need to determine how important accuracy of these predictions is for your organisation. For example, law enforcement and public safety might require a 99% accuracy. For most companies a level of 80% might be acceptable.
- Maximum number of people recognised in an image
By default, maximum number of people is set to 10. You can change this number according to your preference. The higher you have set the required confidence level the fewer faces may be recognised.
