ABSTRACT:
A method and apparatus are disclosed for segmenting character images in an optical image system where the character images have a predetermined pitch. The optical image system generates character information in the form of a successive series of scan lines of data. Profiles of the character images being scanned are generated, and a profile segment meeting certain criteria is selected. The center of the selected profile segment is located, and segmentation points between the character images are established as a linear function of the character image pitch and located center. The segmentation points are integer multiples of the pitch.
