以長短期記憶模型進行筆寫單字辨識

On-Pen Handwritten Word Recognition Using Long Short-Term Memory Model

指導教授 : 周百祥

摘要


近年來,因穿戴式裝置的流行,基於動作感測的手寫辨識研究越來越多,例如空中手寫、智慧筆等等,但是能達到實用水平的應用卻很少。受限於感測器的限制、連續動作的分割難度這些問題,手寫動作辨識很難做有效率的文字輸入。在這篇論文中,我們提出了一種安裝在筆上的新型硬體裝置,搭配以長短期記憶模型(LSTM)為核心的辨識系統,讓使用者能夠用任何他們想拿來寫字的筆,作為一個有效率的文字輸入介面。

This thesis describes a system for text input from handwriting using a conventional pen with a clip-on sensing unit. The clip-on unit is a wireless sensor node that collects data from a triaxial accelerometer and a triaxial gyroscope and transmits it to a conventional personal computer. The host computer then performs segmentation to handle continuous handwriting, followed by LSTM-based classification. Moreover, we use a lexicon-based corrector to increase the accuracy. Experimental results show our proposed system to achieve good accuracy and reasonable latency for interactive use.
