ABSTRACT:
A method for combining multiple digital shape objects contained within a digitized document to obtain a distinct shape or hull dependent on the shapes of the original objects. This shape may thereafter be utilized to simplify storage, recognition, and classification of the digitized documents. The method for combining multiple digital images includes the steps of forming a connected, one-pixel thick boundary around the shape objects contained within a document; and collapsing the boundary around the contained digital objects, the boundary thereby attaining a distinct shape or hull dependent upon the shapes of the digital objects contained within the document. When necessary, pixels are deleted from the boundary to "shrink-wrap" or make taut the boundary around the contained objects.
