Electronic document image resizing

Computer document treatment generally requires specific techniques to handle documents. Among the others one of great interest is resizing. The effect of resizing is more evident when thin lines are included in the document. In this case a high degradation and consequently great loss of information occurs. In this paper different reduction techniques, in terms of computational load and information loss referred to graphics and technical drawings, are compared. Experimental results, related to document treatments, are included in the paper. The results are obtained using a threshold technique optimized for line drawing reduction
