ABSTRACT:
Apparatus for processing digitized images which contain useful image formation data and background features a background supression scheme used to convert each pixel value to preselected values in a smaller range in order to facilitate data processing such as compression and scaling. Provision is made for generating an adaptive or dynamic threshold value, as well as a much more stable background reference threshold value.
