Text-Line Extraction and Character Recognition of Document Headlines With Graphical Designs Using Complementary Similarity Measure
October 1998 (vol. 20 no. 10)
pp. 1103-1109

Abstract—A method for recognizing characters on graphical designs is proposed. A new projection feature that separates text-line regions from backgrounds, and adaptive thresholding in displacement matching are introduced. Experimental results for newspaper headlines with graphical designs show a recognition rate of 97.7 percent.
