Symbolic-Substitution-Based Operations Using Holograms: Multiplication And Histogram Equalization
Abdallah K. Cherri, Mohammad A. Karim · Optical Engineering · 1989
Holographic content-addressable memory is used in an optical symbolic-substitution-based system to realize an efficient and high speed optical multiplier. Such a system is also capable of performing image processing operations. Consequently, it is used to obtain a fast gray-level histogram and histogram equalization of an input image.
