Abstract
A method and apparatus is described in which a document is scanned and the coordinates of each graphic element intercepted along the scan line are analyzed to encode a compact digital representation of the various graphic elements. In one embodiment, detected features of a height less than a first dimension or having both a width less than a desired width threshold and a height less than a desired height threshold are deleted as representative of noise. No data representative of topological or dimensional features is output until after the continued recognition of such features for more than a threshold number of scan lines.
