Ensembles of exemplar-SVMs for video face recognition from a single sample per person |

|---|---|---|
Recognizing the face of target individuals in a watch-list is among the most challenging applications in video surveillance, especially when enrollment is based on one reference still facial image. Besides the limited representativeness of facial models used for matching, the appearance of faces captured in videos varies due to changes in illumination, pose, scales, etc., and to camera inter-operability. A multi-classifier system is proposed in this paper for robust still-to-video face recognition (FR) based on multiple diverse face representations. An individual-specific ensemble of exemplar-SVMs (e-SVMs) classifiers is assigned to each target person, where each classifier is trained using a high-quality reference face still versus many lower-quality faces of non-target individuals captured in videos. Diverse face representations are generated from different patches isolated in facial images and face descriptors that are robust to various nuisance factors (e.g., illumination and pose) commonly encountered in surveillance environments. Discriminant feature subsets, training samples, and ensemble fusion functions are selected using faces of non-target individuals captured in videos of the scene. Experiments on videos from the Chokepoint dataset reveal that the proposed ensemble of e-SVMs outperforms state-of-the-art FR systems specialized for the single sample per person problem. |
