In optical character recognition (OCR) and document analysis many errors are not caused by inadequate classifier power, but by segmentation errors. Besides broken characters, merged characters constitute the major remaining problem. This paper presents an efficient method for segmenting merged characters.

ALPR character segmentation algorithm
2018 IEEE 9th Latin American Symposium on Circuits & Systems (LASCAS), 2018This work presents a character segmentation algorithm for Argentine license plates based on image projection and its respective minima processing to determine the location of each character coordinates. Its tested implementation in C++ achieves a 96.49% success rate on a database of 3023 licenses, taking an average of 6.6 ms for a complete license ...

Strategies in character segmentation: a survey
Proceedings of 3rd International Conference on Document Analysis and Recognition, 2002This paper provides a review of advances in character segmentation. Segmentation methods are listed under four main headings. The operation of attempting to decompose the image into classifiable units on the basis of general image features is called "dissection".

Word and Character Segmentation
2021In the previous chapter, the methods for text detection from natural scene and video image are discussed. To recognize text, the methods require characters. Therefore, this chapter focuses on word and character segmentation based on the space between words and characters.

Character recognition without segmentation
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1995A segmentation-free approach to OCR is presented as part of a knowledge-based word interpretation model. It is based on the recognition of subgraphs homeomorphic to previously defined prototypes of characters. Gaps are identified as potential parts of characters by implementing a variant of the notion of relative neighborhood used in computational ...

Segmentation of Arabic Characters
International Journal of Technology Diffusion, 2011The cursive nature of Arabic writing is the main challenge to Arabic Optical Character Recognition developer. Methods to segment Arabic words into characters have been proposed. This paper provides a comprehensive review of the methods proposed by researchers to segment Arabic characters.

A hybrid approach to character segmentation of gurmukhi script characters
32nd Applied Imagery Pattern Recognition Workshop, 2003. Proceedings., 2004A new approach to segmentation of machine printed Gurmukhi text has been suggested. This approach can easily be extended to other Indian language scripts such as Devnagri and Bangla. Most of the characters in these scripts have horizontal lines at the top called headlines.

In the Optical Character Reader (OCR) system design, the character segmentation technique is important. For example, the Automatic Mail Address Reader is required to manage printed characters of many font types and poor print quality. In this case, OCR performance will be affected by character segmentation technique.

On the segmentation of touching characters
Proceedings of 2nd International Conference on Document Analysis and Recognition (ICDAR '93), 2002In many OCR systems, character segmentation is a necessary preprocessing step for character recognition. It is a critical step because incorrectly segmented characters are not likely to be correctly recognized. The most difficult cases in character segmentation are broken characters and touching characters. The problem of segmenting touching characters

A Character Segmentation Method without Character Verification
2008 International Symposium on Intelligent Information Technology Application Workshops, 2008Nowadays many digital watermarking schemes have been proposed to protect paper-based documents, in which character segmentation is important in both embedding and detecting processes. However, considering the time/cost consuming, the current character segmentation methods used in OCR (optical character recognition) are not suitable for this purpose. In
