Abstract
This paper describes the formation of an arbitrary blurring followed by the use of a filter in a frequency plane to eliminate the blur. The complex space filters produced by the computer-generated method enables one to construct many new and fascinating coding and decoding systems for dilute objects. In this paper several CGH filters, inverse filters, Wiener filters and the Wiener filter of the exponential type, have been developed. All these filters have been experimentally tested as to their capabilities for cryptology and good results have been obtained.
