Zusammenfassung:A method for selecting frames used in face processing includes capturing video data featuring a face of an individual and determining with a processing unit at least one image quality indicator for at least some frames in the video data. The quality indicator is used for selecting a subset of the frames and a sequence of frames is determined corresponding to a movement of a body portion detected in the video data and/or corresponding to a response window during which a response to a challenge should be given. At least one second frame is added to the subset within a predefined interval before or after the sequence and the selected frames are stored in a memory.
