Image enhancement using optical symbolic substitution

Rotation-invariant image sharpening schemes based on Roberts operators, difference operators, Laplacian, and high-frequency emphasis are realized using optical symbolic substitution. Symbolic systems based on both optical content-addressable memory and phase-only holograms are considered for these image enhancement schemes.
