Segmentation of touching characters in upper zone in printed Gurmukhi script

A new technique for segmenting touching characters in upper zone of printed Gurmukhi script has been presented in this paper. The technique is based on the structural properties of the Gurmukhi script characters. Concavity and convexity of the characters has been studied and using top profile projections, the touching characters in upper zone have been segmented. Recognition rate of 91 % has been achieved for segmenting the touching characters in upper zone

A technique for segmentation of Gurmukhi text

Abstract. This paper describes a technique for text segmentation of machine printed Gurmukhi script documents. Research in the field of segmentation of Gurmukhi script faces major problems mainly related to the unique characteristics of the script like connectivity of characters on the headline, two or more characters in a word having intersecting minimum bounding rectangles, multicomponent characters, touching characters which are present even in clean documents. The segmentation problems unique to the Gurmukhi script such as horizontally overlapping text segments and touching characters in various zonal positions in a word have been discussed in detail and a solution has been proposed
