Abstract: An algorithm was proposed to realize image segmentation with subpixel
image based on Niblack and Otsu algorithms. Experimental results showed
that the proposed algorithm can keep the characters′ topological structure,
and yield smooth edge effectively. Compared with the original image
segmentation, this proposed method is more efficient.
