Strategies for Combining On-line and Off-line Information in an On-line Handwriting Recognition System

چکیده
This paper investigates the cooperation of on-line and off-line handwriting word recognition systems. Our goal is to improve a mature on-line recognition system by exploiting the complementary information present in the off-line representation built from on-line signal. After describing the on-line and off-line HMM based handwriting recognition systems, we propose a formal framework, which allows describing different strategies for combining the two HMMs. These schemes are then evaluated on the UNIPEN database, both for isolated character and word recognition tasks.

In order to facilitate the entry of data into the computer and its digitalization, automatic recognition of printed texts and manuscripts is one of the considerable aid to many applications. Research on automatic document recognition started decades ago with the recognition of isolated digits and letters, and today, due to advancements in machine learning methods, efforts are being made to iden...
متن کاملOff-line cursive handwriting recognition compared with on-line recognition
Off-line handwriting recognition has wider applications than on-line recognition, yet it seems to be a harder problem. While on-line recognition is based on pen trajectory data, off-line recognition has to rely on pixel data only. We present a comparison between an off-line and an on-line recognition system using the same databases and system design. Both systems use a sliding window technique ...
متن کاملFrom Off-line to On-line Handwriting Recognition
On-line handwriting includes more information on the time order of the writing signal and on the dynamics of the writing process than off-line handwriting. Therefore, on-line recognition systems achieve higher recognition rates. This can be concluded from results reported in the literature, and has been demonstrated empirically as part of this work. We propose a new approach for recovering the ...
متن کاملHandwriting Recognition of Whiteboard Notes - Studying the Influence of Training Set Size and Type
This paper presents a system for the recognition of on-line whiteboard notes. Notes written on a whiteboard is a new modality in handwriting recognition research that has received relatively little attention in the past. For the recognition we use an offline HMM-recognizer, which is supplemented with methods for processing the on-line data and generating off-line images. The system consists of ...
متن کاملCombining On-Line and Off-Line Bidirectional Long Short-Term Memory Networks for Handwritten Text Line Recognition
In this paper we present a multiple classifier system (MCS) for on-line handwriting recognition. The MCS combines several individual recognition systems based on bidirectional long short-term memory networks. To obtain diverse recognizers, we use different feature sets based on on-line and off-line features. Furthermore, we generate a number of different recognizers by changing the initializati...
