Summary

Public variables

Name	Type	Description
livenessConfidence	Float	The liveness confidence of the passive liveness detection.

Signature	Return Type	Description
encode(to encoder: Encoder)	Void	Encodes the model using the encoder provided. Used to convert the model to JSON.

Public variables

livenessConfidence

@objc final public var livenessConfidence: Float { get }

The liveness confidence of the passive liveness detection.

Range: 0 - 1

Due to the laws of physics and limitations that exists between humans and machines, values will rarely be exactly 1 or 0 but should not be discredited.

The closer the value is to 0 the more the subject is perceived to be a spoof. The closer the value is to 1 the more the subject is perceived to be genuine.

Public methods

encode(to encoder: Encoder)

override final public func encode(to encoder: Encoder) throws

This function also calls its super function

Encodes the model using the encoder provided. Used to convert the model to JSON.
