Abstract

In this research work, we have proposed a segmentation technique for words and characters of Devanagari offline handwritten scripts. Due to complex structures and high unevenness in writing styles, recognition of words and characters from the unconstrained scripts has become a burning vicinity of interest for researchers. The proposed Pixel Plot and Trace and Re-plot and Re-trace (PPTRPRT) technique extracts text region from Devanagari offline handwritten scripts and lead iterative processes for segmentation of text lines along with skew and de-skew operations. The outcomes of iterations are used in pixel-space-based word segmentation, and the segmented words are used in segmentation of characters. Moreover, PPTRPRT perform various normalization steps to allow deviation in pen breadth and slant in inscription. Investigational outcome shows that the proposed technique is competent to segment characters from Devanagari offline handwritten scripts, and accuracy of outcomes is up to 99.578 %.
