Applications of Optical Symbolic Substitution to Image Processing: Median Filters
Abdallah K. Cherri, Mohammad A. Karim · 1989
Symbolic substitution (SS) based architectures [1] are actively sought for designing optical computing systems capable of processing binary data in parallel. The symbolic substitution is a two-dimensional parallel processing technique which maps a given pattern (referred to as search pattern) into a new pattern (referred to as scribe pattern).
