Toward high-performance online HCCR: a CNN approach with DropDistortion, path signature and spatial stochastic max-pooling

no code implementations24 Feb 2017 Songxuan Lai, Lianwen Jin, Weixin Yang

This paper presents an investigation of several techniques that increase the accuracy of online handwritten Chinese character recognition (HCCR).

Online Signature Verification using Recurrent Neural Network and Length-normalized Path Signature

no code implementations19 May 2017 Songxuan Lai, Lianwen Jin, Weixin Yang

Inspired by the great success of recurrent neural networks (RNNs) in sequential modeling, we introduce a novel RNN system to improve the performance of online signature verification.

EnsNet: Ensconce Text in the Wild

3 code implementations3 Dec 2018 Shuaitao Zhang, Yuliang Liu, Lianwen Jin, Yaoxiong Huang, Songxuan Lai

The feature of the former is first enhanced by a novel lateral connection structure and then refined by four carefully designed losses: multiscale regression loss and content loss, which capture the global discrepancy of different level features; texture loss and total variation loss, which primarily target filling the text region and preserving the reality of the background.

Offline Writer Identification based on the Path Signature Feature

no code implementations3 May 2019 Songxuan Lai, Lianwen Jin

In this paper, we propose a novel set of features for offline writer identification based on the path signature approach, which provides a principled way to express information contained in a path.

SynSig2Vec: Learning Representations from Synthetic Dynamic Signatures for Real-world Verification

no code implementations13 Nov 2019 Songxuan Lai, Lianwen Jin, Luojun Lin, Yecheng Zhu, Huiyun Mao

To tackle this issue, this paper proposes to learn dynamic signature representations through ranking synthesized signatures.

PageNet: Towards End-to-End Weakly Supervised Page-Level Handwritten Chinese Text Recognition

4 code implementations29 Jul 2022 Dezhi Peng, Lianwen Jin, Yuliang Liu, Canjie Luo, Songxuan Lai

Utilizing the proposed weakly supervised learning framework, PageNet requires only transcripts to be annotated for real data; however, it can still output detection and recognition results at both the character and line levels, avoiding the labor and cost of labeling bounding boxes of characters and text lines.
