An Introduction to Handwritten Character and Word Recognition
L. C. Jain, Beatrice Lazzerini · 2020
There is a worldwide interest in the development of handwritten character and word recognition systems. These systems are used in many situations such as recognition of postcodes, interpretation of amount and verification of signature on bank checks, and law enforcement on public roads. This chapter introduces principles of handwriting recognition for on-line and off-line systems. It discusses some considerations about performance evaluation of a handwriting recognition system. Handwriting recognition systems acquire data by means of either offline devices or on-line devices. Most current approaches to off-line handwriting recognition consist of three main phases, namely, preprocessing, segmentation, and recognition. Recognition of handwritten characters is undoubtedly the basic task of most automatic reading systems. Most approaches to on-line handwriting recognition fall into two main categories: analysis by synthesis, which is based on the modeling of handwriting generation, and application of off-line recognition methods to on-line recognition.
