4. The method of claim 1 , wherein isolating the plurality of glyph-based character representations includes: detecting character gaps in the line of glyph-based character representations; creating a histogram of distances for the detected character gaps; constructing a graph according to the detected character gaps; assigning a penalty to arcs of the graph wherein the penalty is based in part on the histogram of distances; and selecting a path in the graph associated with the character cells based on said penalty and arcs of the graph.
