A Combinatorial Solution to Point Symbol Recognition

A Visual Approach to Sketched Symbol Recognition

There is increasing interest in building systems that can automatically interpret hand-drawn sketches. However, many challenges remain in terms of recognition accuracy, robustness to different drawing styles, and ability to generalize across multiple domains. To address these challenges, we propose a new approach to sketched symbol recognition that focuses on the visual appearance of the symbol...

A combinatorial solution to intertwined recurrences

Musings on Symbol Recognition

Symbol recognition is a field within graphics recognition to which a lot of efforts have already been devoted. However, a document analysis expert who is more familiar with OCR might rightfully wonder what exactly we call a symbol and how symbol recognition differs from basic character recognition. Our feeling is that the problem is very different because of the much higher number and variety o...

Graphical symbol recognition

The chapter focuses on one of the key issues in document image processing i.e., graphical symbol recognition. Graphical symbol recognition is a sub-field of a larger research domain: pattern recognition. The chapter covers several approaches (i.e., statistical, structural and syntactic) and specially designed symbol recognition techniques inspired by real-world industrial problems. It, in gener...

A Combinatorial Approach to Knot Recognition

This is a report on our ongoing research on a combinatorial approach to knot recognition, using coloring of knots by certain algebraic objects called quandles. The aim of the paper is to summarize the mathematical theory of knot coloring in a compact, accessible manner, and to show how to use it for computational purposes. In particular, we address how to determine colorability of a knot, and p...
