In-air handwritten Chinese text recognition with temporal convolutional recurrent network
作者:
Highlights:
• We present a 3D touchless in-air handwritten Chinese text recognition system for the first time.
• We constructed the first publicly available in-air handwritten Chinese text dataset, named IAHCT-UCAS2018, for the community.
• A novel architecture, named the temporal convolutional recurrent network, is proposed for online handwritten Chinese text recognition, which achieves the competitive performance compared with the state-of-the-art methods on CASIA-OLHWDB2 and ICDAR-2013.
• Compared with state-of-the-art architecture, TCRN not only avoids the domain-specific knowledge for feature image extraction, but also attains higher training efficiency with a more compact model.
• Empirically, TCRN also outperforms the single recurrent neural network with faster prediction.
