Abstract:
A method for transmitting a document image stored in a memory at a server workstation to a client workstation, comprising the steps of:receiving a bitmap representation of a hardcopy document in the memory to define the document image; segmenting the document image into a set of layout objects; each layout object in the set of layout objects being one of a plurality of layout object types; each of the plurality of layout object types identifying a structural element of the document image; computing a set of attributes for each layout object in the set of layout objects; the attributes computed for each layout object having values that quantify properties of a structural element and identify spatial relationships with other segmented layout objects in the document image; receiving a user input that identifies a selected first attribute of a layout object; dividing the set of layout objects into a first subset and a second subset of layout objects, said dividing step including layout objects with the selected first attribute in the first subset of layout objects; the second subset of layout objects including those layout objects in the set of layout objects not in the first subset of layout objects; and transmitting from the server workstation to the client workstation the first subset of layout objects at a first resolution and the second subset of layout objects at a second resolution.
