MultiLangKD-OCR: Knowledge Distillation for Arabic, Persian and Pashto OCR

Optical character recognition (OCR) faces severe challenges when dealing with right-to-left (RTL) multilingual documents, especially for Arabic, Persian and Pashto - these languages significantly reduce the recognition accuracy of existing models due to complex ligated structures, character overlap and unique symbols.

An Enhanced Arabic OCR Degraded Text Retrieval Model

2013
This paper provides a new model enhancing the Arabic OCR degraded text retrieval effectiveness. The proposed model based on simulating the Arabic OCR recognition mistakes on a word based approach. Then the model expands the user search query using the expected OCR errors.

Secure Arabic Handwritten CAPTCHA Generation Using OCR Operations

2016 15th International Conference on Frontiers in Handwriting Recognition (ICFHR), 2016
Handwritten CAPTCHAs can be generated from pre-written or synthesized words, with added distortions and noise to survive OCR attacks. This paper takes a different approach for generating CAPTCHAs: use OCR operations themselves to secure the CAPTCHAs.

A Metaheuristic Algorithm for OCR Baseline Detection of Arabic Languages

2015
Preprocessing is a very important part of cursive languages Optical Character Recognition (OCR) systems. Thus, baseline detection, which is one of the main parts of the preprocessing operation, plays a basic role on OCR systems; improvement on baseline detection could be absolutely useful for decreasing errors in recognition words.

Arabic Optical Character Recognition (OCR) Evaluation in Order to Develop a Post-OCR Module

2011
Abstract : Optical character recognition (OCR) is the process of converting an image of a document into text. While progress in OCR research has enabled low error rates for English text in low-noise images, performance is still poor for noisy images and documents in other languages.
