Multi-face Recognition at a Distance Using Light-Field Camera

In this paper, we address the problem of identifying multiple faces present at different distance using Light-Field Camera (LFC). Since a LFC can provide different focus (or depth) images in single capture, we are motivated to investigate its applicability to identify multiple faces at a distance by exploring its all-in-focus property. We first collect the new face dataset using LFC and then carry out extensive experiments to evaluate the merits and demerits of LFC, especially in identifying multiple faces at a distance. We explore the applicability of light field camera for face recognition applications in at-a-distance surveillance scenario.
