Math spotting in technical documents using handwritten queries
- in Proc. Work. Pen-Based Mathematical Computation, Grand
, 2009
"... Content-based image retrieval (CBIR) for documents has been studied for a long time [3]. It focuses on indexing and retrieval capabilities in a large set of document images and provides a convenient way for people to access the information in these images, which means retrieving document images by t ..."

called X Y tree has been usually used to retrieve query image by comparing tree structure [1]. Based on pixel projection, the X-Y tree can be gotten by X-Y cutting (Figure 1b), which cuts the page in vertical and horizontal directions alternatively. Figure 1 shows the process of getting a X-Y tree of a

Math spotting: Retrieving math in technical documents using handwritten query images
- In Proc. Int’l Conf. Document Analysis and Recognition
, 2011
"... Abstract—A method for locating mathematical expressions in document images without the use of optical character recognition is presented. An index of document regions is produced from recursive X-Y trees produced for each page in the corpus. Queries are provided as images of handwritten expressions, ..."

Koios++: A Query-Answering System for Handwritten Input
"... Abstract-In this paper we propose KOIOS++, which automatically processes natural language queries provided by handwritten input. The system integrates several recent achievements in the area of handwriting recognition, natural language processing, information retrieval, and human computer interacti ..."

Studies of Radical Model for Retrieval of Cursive Chinese Handwritten Annotations
"... Abstract. Our research focuses on Chinese online ink matching that tries to match handwritten annotations with handwritten queries without attempting to recognize them. Previously, we proposed a semantic matching scheme that uses elastic matching with a dynamic programming approach based on the radi ..."

Handwritten word-image retrieval with synthesized typed queries
- 10TH INTERNATIONAL CONFERENCE ON DOCUMENT ANALYSIS AND RECOGNITION
, 2009
"... We propose a new method for handwritten word-spotting which does not require prior training or gathering examples for querying. More precisely, a model is trained “on the fly ” with images rendered from the searched words in one or multiple computer fonts. To reduce the mismatch between the typed-te ..."

Towards Query-by-Speech Handwritten Keyword Spotting
"... Abstract—In this paper, we present a new querying paradigm for handwritten keyword spotting. We propose to represent hand-written word images both by visual and audio representations, enabling a query-by-speech keyword spotting system. The two representations are merged together and projected to a c ..."

Indexing of Handwritten Document Images
"... An important problem in the management of scanned handwritten document image collections, is their indexing or retrieval based on word queries. This paper presents a method for fast localization of query words in handwritten images by an adaptation of the principle of geometric hashing. Specifically ..."

Lexical Error Compensation in Handwritten-Based Mathematical Information Retrieval
"... Abstract. Entering mathematical queries, in general, can be a demanding task. Mathematical notation is two-dimensional and cannot be easily typed with a standard QWERTY keyboard. Handwriting appears to be the most intuitive and promising method to express mathematical queries. Recognition technology ..."
Abstract
- Add to MetaCart
technology for handwritten mathematical notation has never been applied in math search. The objective of this research is to design and implement an automated symbol-recognition error compensation system for the handwritten-based query processing. To achieve this objective, we have designed and implemented a
Unconstrained handwritten document retrieval

Abstract With the ever-increasing growth of the World Wide Web, there is an urgent need for an efficient information retrieval system that can search and retrieve handwritten documents when presented with user queries. However, unconstrained handwriting recognition remains a challenging task with i ..."
