Abstract

An approach for segmentation of handwritten touchingnumeral strings is presented in this paper. A neural networkhas been designed to deal with various types of touchingobserved frequently in numeral strings. A numeral stringimage is split into a number of line segments while strokeextraction is being performed and the segments are representedwith straight lines. Four types of primitive are definedbased on the lines and used for representing the numeralstring in more abstractive way and extracting clueson touching information from the string. Potential segmentationpoints are located using the neural network by activeinterpretation of the features collected from the primitives.Also, the run-length coding scheme is employed for efficientrepresentation and manipulation of images. On a test setcollected from real mail pieces, the segmentation accuracyof 89.1% was achieved, in image level, in a preliminary experiment.
