Abstract: Highlights•A modality-invariant feature is extracted for Heterogeneous face recognition.•Edges are captured using a new illumination-invariant image representation.•Novel local circular quaternary pattern is used to measure the local texture.•Novel quaternary pattern of local maximum quotient for face recognition.•Robust handcrafted features combined with deep learning gives better accuracy.
