    摘要:

    手寫(xiě)漢字識別是手寫(xiě)漢字輸入的基礎。目前智能設備中的手寫(xiě)漢字輸入法無(wú)法根據用戶(hù)的漢字書(shū)寫(xiě)習慣,動(dòng)態(tài)調整識別模型以提升手寫(xiě)漢字的正確識別率。通過(guò)對最新深度學(xué)習算法及訓練模型的研究,提出了一種基于用戶(hù)手寫(xiě)漢字樣本實(shí)時(shí)采集的個(gè)性化手寫(xiě)漢字輸入系統的設計方法。該方法將采集用戶(hù)的手寫(xiě)漢字作為增量樣本,通過(guò)對服務(wù)器端訓練生成的手寫(xiě)漢字識別模型的再次訓練,使識別模型能夠更好地適應該用戶(hù)的書(shū)寫(xiě)習慣,提升手寫(xiě)漢字輸入系統的識別率。最后,在該理論方法的基礎上,結合新設計的深度殘差網(wǎng)絡(luò ),進(jìn)行了手寫(xiě)漢字識別的對比實(shí)驗。實(shí)驗結果顯示,通過(guò)引入實(shí)時(shí)采集樣本的再次訓練,手寫(xiě)漢字識別模型的識別率有較大幅度的提升,能夠更有效的滿(mǎn)足用戶(hù)在智能設備端對手寫(xiě)漢字輸入系統的使用需求。

    Abstract:

    Handwritten Chinese character recognition is the basis of handwritten Chinese characters input system. At present, Handwritten Chinese character input method in smart devices can not adjust the recognition model dynamically according to the user"s Chinese writing habits in order to improving the correct recognition rate of handwritten Chinese characters. Through the study of the latest deep learning algorithm and training model, a design method of handwritten Chinese character input system based on the real-time acquisition of handwritten Chinese characters samples is proposed. This method will capture the user"s handwriting Chinese characters as the increment of sample. Through re-training the pre-training model, the recognition model can better fit the user"s writing habits, and enhance the recognition rate of the Chinese characters handwritten input system. Finally, on the basis of the theoretical method and combining the new design of depth residual network, a comparative experiment of handwritten Chinese character recognition is carried out. The experimental results show that by introducing real-time samples to training, the rate of recognition of handwritten Chinese characters recognition model is improved. It can more effectively satisfy the user"s demand for handwriting Chinese character input system at the intelligent terminal.
