Cascade ensembles for liveness detection

Abstract

Systems and methods for performing liveness detection. A method includes transmitting an image or a video by a threat detector to one or more filters for a first level check for detecting a threat based on analysis of certain characteristics, transmitting the image or the video to one or more special models for a second level check, wherein the one or more special models are configured for detecting multiple types of threats on the image or the video, transmitting the image or the video to a general model ensemble for a third level check to classify the image or the video according to individual features into original and fake, and in response to detecting the threat, registering the threat by the threat detector.
