An Image-Based Measure for Evaluation of Mathematical Expression Recognition

Álvaro Muñoz, Francisco; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel (Springer, 2013)

Mathematical expression recognition is an active research field that is related to document image analysis and typesetting. In this study, we present a novel global performance evaluation measure for mathematical expression ...
An integrated grammar-based approach for mathematical expression recognition

Álvaro Muñoz, Francisco; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel (Elsevier, 2016)

Automatic recognition of mathematical expressions is a challenging pattern recognition problem since there are many ambiguities at different levels. On the one hand, the recognition of the symbols of the mathematical ...
Generation of Hypergraphs from the N-Best Parsing of 2D-Probabilistic Context-Free Grammars for Mathematical Expression Recognition

Noya, Ernesto; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel (IEEE, 2021-01-15)

[EN] We consider hypergraphs as a tool obtained with bidimensional Probabilistic Context-Free Grammars to compactly represent the result of the n-best parse trees for an input image that represents a mathematical expression. ...
IMEGE: Image-based Mathematical Expression Global Error

Álvaro Muñoz, Francisco; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel (Universitat Politècnica de València, 2011-11-16)

Mathematical expression recognition is an active research eld that is related to document image analysis and typesetting. Several approaches have been proposed to tackle this problem, and automatic methods for performance ...
Indexación y búsqueda de expresiones matemáticas a gran escala en corpus masivos de documentos impresos

Noya García, Ernesto (Universitat Politècnica de València, 2020-09-04)

[ES] En la actualidad existen grandes bases de datos de documentos científicos impresos digitalizados, muchos de los cuales incluyen expresiones matemáticas. La búsqueda de información textual en estos documentos ...
Off-line Recognition of Printed Mathematical Expressions Using Stochastic Context-Free Grammars

Álvaro Muñoz, Francisco (Universitat Politècnica de València, 2011-11-29)

Off-line recognition of printed mathematical expressions consists of three major steps: segmentation, symbol recognition and structural analysis. In this work we study an approach based on a twodimensional extension of ...
Recognition of on-line handwritten mathematical expressions using 2D stochastic context-free grammars and hidden Markov models

Álvaro Muñoz, Francisco; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel (Elsevier, 2014-01)

[EN] This paper describes a formal model for the recognition of on-line handwritten mathematical expressions using 2D stochastic context-free grammars and hidden Markov models. Hidden Markov models are used to recognize ...
The IBEM dataset: A large printed scientific image dataset for indexing and searching mathematical expressions

Anitei, Dan; Sánchez Peiró, Joan Andreu; Benedí Ruiz, José Miguel; Noya García, Ernesto (Elsevier, 2023-08)

[EN] Searching for information in printed scientific documents is a challenging problem that has recently received special attention from the Pattern Recognition research community. Mathematical expressions are complex ...
