Color coding of spatial frequencies using incoherent optical processing
1979
Applied Optics
Preserved Fulltext
An incoherent optical processing technique for color coding the spatial frequency content of an input is described. Experimental results and comparison with the output of a coherent filtering system are discussed. Possible applications such as texture recognition in aerial imagery or radiography analysis are suggested.
