TLDR
A novel approach towards character segmentation in a handwritten document is proposed based on the vertex characterization of outer isothetic polygonal covers so that each cover corresponds to a particular word or part of a word.Abstract:
Segmentation of cursive handwriting is one of the most challenging problems in the area of handwritten character recognition. In this paper, we propose a novel approach towards character segmentation in a handwritten document. It is based on the vertex characterization of outer isothetic polygonal covers so that each cover corresponds to a particular word or part of a word. The proposed method has the potential to segment skewed text without deskewing them. Experiment is done on several Bangla handwritings of different individuals. The average success rate is 96.04\%. This method can be considered as a significant preprocessing step towards the development of a handwritten Bangla OCR system.read more

Shape decomposition-based handwritten compound character recognition for Bangla OCR
Rahul Pramanik,Soumen Bag +1 more
TL;DR: This paper proposes a novel shape decomposition-based segmentation technique to decompose the compound characters into prominent shape components, which reduces the classification complexity in terms of less number of classes to recognize, and at the same time improves the recognition accuracy.

Construction of isothetic covers of a digital object: A combinatorial approach
TL;DR: A combinatorial algorithm is presented for varying grid sizes, which is free of any backtracking and can produce the isothetic cover of a connected component in a time linear in the length of the perimeter of the cover.
