Abstract :
The global interpolation (GIM) we propose evaluates segment pattern continuity and connectedness to produce characters with smooth edges while interpreting blank or missing segments, e.g., in extracting a handwritten character overlapping a border, correctly. Characters contacting a border, for example, are extracted after the border itself is labeled and removed. The absence of character segments is then interpolated based on segment continuity. Interpolated segments are relabeled and checked for matching against the original labeled pattern. If a match cannot be made, segments are reinterpolated until they can be identified. Experimental results show that global interpolation interprets the absence of character segments correctly and generates with smooth edges
