Spatiotemporal local orientational binary patterns for facial expression recognition from video sequences

Abstract

On account of encoding the binary result of the differential values between the central pixel and its neighbors, the local binary pattern (LBP) cannot describe more detailed information. Aiming at this issue, local orientational binary patterns (LOBP) is proposed. LOBP encodes the variations of the neighborhood orientational difference, which represents… (More)
