A novel local enhancement technique for rebuilding Broken characters in a degraded Kannada script

Degraded character recognition is one of the most challenging topic in the field of Kannada character recognition. The degraded characters which are broken and deformed will have missing features and will be difficult for any recognition method. Rebuilding the degraded character is very important for better recognition. This paper proposes a novel method to rebuild the broken characters. These characters are thinned and the endpoints of the lines are obtained. The line segments are effectively rebuilt so as to preserve the degraded character. Experimental results on this method are presented to establish its efficiency.
