Abstract: A liveness test method includes detecting a face region in an input image; generating, based on the detected face region, weight map data related to a face location in the input image; generating concatenated data by concatenating the weight map data with feature data generated from an intermediate layer of a liveness test model or image data of the input image; and generating a liveness test result based on a liveness score generated by the liveness test model provided with the concatenated data.
