Description: This method utilizes a sequential-free box dicretization method to localize the text instances. Only public datasets are used for pre-training, including LSVT, ArT and MLT. Multi-scale testing and model ensemble are used to generate the final result. The result is submitted by the researchers from South China University of Technology, Northwestern Polytechnical University, The University of Adelaide, Lenovo and Huawei. The researchers are Yuliang Liu, Hao Chen, Shuaitao Zhang, Lele Xie, Dezhi Peng, Weihong Ma, Tong He, Chongyu Liu, Xiangle Chen, Canjie Luo, Qingxiang Lin, Lianwen Jin, Chunhua Shen, Yaqiang Wu and Liangwei Wang.
