在维吾尔文联机手写识别过程的训练阶段,单词被切分成字母,经过特征提取和聚类形成特征向量作为模型的输入。构造出以字符为基元的隐马尔可夫模型(HMM),将其嵌入到识别字典网络中。通过基于HMM的分类识别器,最终得到识别结果。首次将消除延迟笔画、建立有延迟笔画和无延迟笔画的字典的方法应用于维吾尔文手写识别中,取得了较高的识别率。
在維吾爾文聯機手寫識彆過程的訓練階段,單詞被切分成字母,經過特徵提取和聚類形成特徵嚮量作為模型的輸入。構造齣以字符為基元的隱馬爾可伕模型(HMM),將其嵌入到識彆字典網絡中。通過基于HMM的分類識彆器,最終得到識彆結果。首次將消除延遲筆畫、建立有延遲筆畫和無延遲筆畫的字典的方法應用于維吾爾文手寫識彆中,取得瞭較高的識彆率。

During the process of the on-line Uyghur handwriting recognition, a word is segmented into characters at the training stage. Passing the state of feature extraction and clustering, each character is entirely transformed into a feature vector as the input of the models. Hidden Markov Model(HMM)for modeling the Uyghur characters as primitives is embedded in a recognition lexicon network. Then through the classification identifier based on HMM and finally the results are obtained. The delayed strokes removed and the dictionaries with and without the delayed strokes constructed which are applied in the Uyghur handwriting recog-nition are introduced firstly, and higher recognition rate is obtained.
