Abstract: Highlights•Our CKD method uses inter-class info from face images to boost periocular recognition.•CKD and learned-label smoothing equivalence, with a novel sparsity regularizer, reveals CKD’s principal mechanisms.•Our CKD method outperforms baselines, excelling in challenging periocular benchmarks, showcasing state-of-the-art performance.
