In aquaculture, accurate and automatic quantification of fish behaviour can provide useful
data input for production management and decision‐making. In recent years, with the focus …

We propose a toolkit to generate structured synthetic documents emulating the actual
document production process. Synthetic documents can be used to train systems to perform …

This work focuses on the layout analysis of historical handwritten registers, in which local
religious ceremonies were recorded. The aim of this work is to delimit each record using few …

In this work, we study the use of Convolutional Neural Networks for counting the number of
records in each page of an historical handwritten document. The initial network training is …

We study the task of document layout analysis based on two-dimensional context-free
grammars. We first identify a subclass of the grammars sufficient for a document structure …

This paper proposes the use of two-dimensional context-free grammars (2DCFGs) for layout
analysis of PDF documents. In Japan, audio textbooks have been available for students with …

Document image understanding involves several tasks including, among others, the layout
analysis of historical handwritten and the symbol recognition in graphical documents. The …

We study properties of a two-dimensional grammar introduced recently for use in document
analysis and recognition. The grammar is obtained from the two-dimensional context-free …

The thesis comprises a collection of selected publications preceded by an introductory text. It
studies methods for structural analysis, which is a stage of structural pattern recognition. Two …
