The Reduction of Memory and the Improvement of Recognition Rate for HMM On-Line Handwriting Recognition
A. Funada, Daigo Muramatsu, Takashi Matsumoto · 2004
The purpose of this project is two fold. The first purpose is to reduce the memory size of our previous handwriting recognition algorithm based on an HMM using self-organizing map (SOM) density tying. The second is to improve recognition capability by incorporating additional information. SOM density tying reduced the dictionary size to 1/7 of the original size, with a recognition rate of 90.45%, only slightly less than the original recognition rate of 91.51%. Our additional feature increased recognition capability to 91.34%.
