Writer style detection and automatic prototype creation for on-line handwriting recognition

摘要

A handwriting recognition system is set forth for creating a user prototype set. Writings of an alphabet set are collected from a plurality of writers. The collected writings are classified into subsets of the alphabet set based on different writing styles. There are created j, where j is an integer greater than or equal to 2, prototype style sets for each of the subsets of the alphabet set. A default set of characters is created for characters that do not belong to any of the subsets. Less than a complete alphabet set of writings from a user is sampled. Each character of the sampled writings of the user are compared with the j prototype style sets to determine which user written characters match one or more of the j prototype style sets. The user written characters and the matched prototype style sets and the default set are then merged to form a user prototype set for the user.
