Document Retrieval In OCR-Scanned Text
The use of a document retrieval system (PADRE) for the Fujitsu AP1000 in processing known-item search queries over OCR-scanned documents is reported. Retrieval performance of an initial set of queries is shown to deteriorate signi cantly over scanned data with a character error rate of 5%. A preprocessor is used to augment queries with terms which can be derived from original terms using charac...
متن کاملRetrieving Images of Scanned Text Documents
Information retrieval is the task of nding documents, usually text, which are relevant to a user's information need. A conventional approach to information management of paper documents is normally based on classifying them into a hierarchical classiication structure. More recently we have seen electronic document management systems which manage scanned images of documents in the same way as pa...
متن کاملText Recognition and Retrieval in Natural Scene Images
In the past few years, text in natural scene images has gained potential to be a key feature for content based retrieval. They can be extracted and used in search engines, providing relevant information about the images. Robust and efficient techniques from the document analysis and the vision community were borrowed to solve the challenge of digitizing text in such images in the wild. In this ...
متن کاملLanguage Determination: Natural Language Processing from Scanned Document Images
Many documents are available to a computer only as images from paper. However, most natural language processing systems expect their input as character-coded text, which may be difficult or expensive to extract accurately from the page. We describe a method for converting a document image into character shape codes and word shape tokens. We believe that this representation, which is both cheap ...
متن کاملText Extraction from Complex Natural Images
The rapid growth in communication technology has led to the development of effective ways of sharing ideas and information in the form of speech and images. Understanding this information has become an important research issue and drawn the attention of many researchers. Text in a digital image contains much important information regarding the scene. Detecting and extracting this text is a diff...
