Abstract
Due to widespread applications, availability of large intra-personal variations in video and limited information content in still images, video-based face recognition has gained significant attention. Unlike still face images, videos provide abundant information that can be leveraged to address variations in pose, illumination, and expression as well as enhance the face recognition performance. This paper presents a video-based face recognition algorithm that computes a discriminative video signature as an ordered list of still face images from a large dictionary. A three-stage approach is proposed for optimizing ranked lists across multiple video frames and fusing them into a single composite ordered list to compute the video signature. This signature embeds diverse intra-personal variations and facilitates in matching two videos with large variations. For matching two videos, a discounted cumulative gain measure is utilized, which uses the ranking of images in the video signature as well as the usefulness of images in characterizing the individual in the video. The efficacy of the proposed algorithm is evaluated under different video-based face recognition scenarios such as matching still face images with videos and matching videos with videos. The efficacy of the proposed algorithm is demonstrated on the YouTube faces database and the MBGC v2 video challenge database that comprise different types of video-based face recognition challenges such as matching still face images with videos and matching videos with videos. Performance comparison with the benchmark results on both the databases and a commercial face recognition system shows the efficiency of the proposed algorithm for video-based face recognition. © 2014 IEEE.
