Online and Offline Vocabulary Correction while using a Digital Pen

Abstract

This thesis is a requirement for the completion of my double degree with Charles University and University of Nancy (France) under the Erasmus Mundus masters program in Language and Communication Technology. The topic was provided by Prof. Abdel BelaÄd along with Actimage Company and has been completed and successfully defended at University of Nancy under their supervision. After the defense in France, I came here to Prague and worked with my co-supervisor Dr. Václav Hlaváč to improve the text of the thesis to meet the standards of Charles University in order to defend it in Prague. The aim of this work is to study some helpful handwriting correction marks and propose a system that automatically incorporates the corrections made by the writer while writing with a digital pen. The problem is complex because the corrections have to be at the same time readable by the writer and by the machine. Even detecting a free řowing line of handwritten text has not been understood completely by machines. The spatial relations between the correction marks and the text line are easily detected by the writers and readers and hence systematic to them, yet for machines this detection is a huge challenge. Humans have an intelligence that is hard to mimic by machines. This seemingly systematic writing has not been studied in...
