title: Monochrome digital image enhancement.
abstract: The use of digital computers as an aid in the enhancement of monochrome imagery is explored. Point processes, spatial processes, and artifact generation are discussed. The former includes single pixel nonlinear mappings for better visual response. Spatial processes include both linear and nonlinear filtering techniques in the Fourier and singular value decomposition domains of an image. Finally, the generation of possible artifacts by enhancement processes is discussed. Numerous pictorial examples illustrating all the techniques developed are included throughout the paper.
