OCR Post-Processing for Low Density Languages
We present a lexicon-free post-processing method for optical character recognition (OCR), implemented using weighted finite state machines. We evaluate the technique in a number of scenarios relevant for natural language processing, including creation of new OCR capabilities for low density languages, improvement of OCR performance for a native commercial system, acquisition of knowledge from a...
متن کاملSecurity Filtering of Medical Images Using Ocr
Before digital medical images in computer-based patient record systems can be distributed online, it is necessary for confidentiality reasons to eliminate patient identification information that appears in the images. We present an automatic security filtering algorithm for on-line medical image distribution using Daubechies' wavelets [Dau92] and Optical Character Recognition (OCR). The system ...
متن کاملMultilevel Correction of Ocr of Medical Texts
In the paper the idea of the multilevel correction of the results handwriting OCR of medical texts is investigated. The correction is performed according to different levels of linguistic knowledge. Three types of models, namely: the n-gram Language Models of word form and base form sequences, the morpho-syntactic model based on a tagger and the model of correction by parsing are presented and ...
متن کاملOptical Font Recognition for Multi-Font OCR and Document Processing
In this paper we present a Multi-font OCR system to be employed for document processing, which performs, at the same time, both the character recognition and the font-style detection of the digits belonging to a subset of the existing fonts. The detection of the font-style of the document words can guide a rough automatic classification of documents, and can also be used to improve the characte...
متن کاملText Pre-processing and Text Segmentation for OCR
Optical Character Recognition (OCR) systems have been effectively developed for the recognition of printed script. The accuracy of OCR system mainly depends on the text preprocessing and segmentation algorithm being used. When the document is scanned it can be placed in any arbitrary angle which would appear on the computer monitor at the same angle. This paper addresses the algorithm for corre...
