The facial recognition feature in Canto allows for the user to choose a Confidence Level to recognize the faces at.  The higher the confidence level, the more accurate the feature will be, but less faces may be identified.  The lower the confidence level, the less accurate the feature will be, but more faces will be identified.

Users can adjust the confidence level depending on the size of their Canto library.

The Reidentify Faces feature will re-analyze your entire Canto library to recognize faces.  This is recommended to alter the amount of faces and accuracy of faces recognized.  

Note: this feature removes the names entered for all faces.

The button will remain Grey while the software is identifying faces, and will reappear as normal once the process has completed.  Admins will also receive an Email Notification once the process is over.

To Remove Faces that you have identified in your Canto Library, uncheck the box "Setup Facial Recognition to Identify People from and Image."  Then, select "Remove Faces."  This feature will completely remove the faces previously identified.
