There are two primary functions within this class. The first one is verifyFace and the second is verifyLiveness.

This function performs 1:1 (One-on-One) face verification using a selfie photo or selfie video against a reference face image.

public JObject verifyFace(string referenceFaceImage, string facePhoto, string faceVideo = "")

Here are the input and output parameters defined against this function.

Type (In/Out)	Name	Description
System.string - [In]	referenceFaceImage	This can be a file path, base64 content, URL, or cache reference face image against which the target face over the picture or video must be verified.
System.string - [In]	facePhoto	This parameter is a face image that can be a file path, base64 content or URL, or cache reference mapped to the referenceFaceImage for verification purposes.
System.string - [In]	faceVideo	This parameter is a face video that can be a file path, base64 content, or URL mapped to the referenceFaceImage for verification purposes. The function will use the BLANK value if the parameter is left out during execution.
JObject - [Out]	N/A	The entire verification object is streamed into `resp` named parameter and returned.

This function enables users to perform standalone liveness checks on selfie photos or videos.
