Content Moderation:Face comparison

Usage notes

Face comparison supports synchronous detection and asynchronous detection.

• If you use synchronous face comparison, the detection results are returned in real time. For more information about the related parameters, see Synchronous moderation.

• If you use asynchronous face comparison, you must poll the detection results or configure a callback notification to receive the detection results. For more information about the related parameters, see Asynchronous moderation.
