Description: We are from Tencent-DPPR (Data Platform Precision Recommendation) Team. We first recognize text lines and their character-level language types using ensemble results of several recognition models, which based on CTC/Seq2Seq and CNN with self-attention/RNN. After that, we identify the language types of recognized results based on statics of MLT-2019 and Wikipedia corpus.

Description: We used area block feature information using images on multiple scales.This model has 4 scales and 8 branches.We also used some data augments and improved ROI pooling.Finally, we used three training sets(mlt17, mlt19_train, mlt19_val).
