CompareFaces

Source: src/AWS/Rekognition/CompareFaces.ts

Runtime binding for rekognition:CompareFaces — compare the largest face in a source image against faces in a target image and return match confidence.

The binding takes no arguments and grants the function rekognition:CompareFaces on * (Rekognition data-plane resources such as collections, users, and jobs are routinely created at runtime, so their identifiers are unknown at deploy time). Provide the implementation with Effect.provide(AWS.Rekognition.CompareFacesHttp).
