CURSIVE WORD REFERENCE LINE DETECTION

This paper proposes a novel method in detecting the four reference lin es of a cursive word at any skew angle. The proposed method is rotatio n independent because the detection is based on points determined by t heir relative positions between the outer contour of a cursive word an d its convex hull. Features like bounding box, contour area, convex hu ll and furthest points are used in detecting and grouping these points . The reference lines are detected by searching for suitable peaks in the Hough transformation space of these points. Encouraging experiment al results have been obtained.
