Description: Tencent-DPPR (Data Platform Precision Recommendation) Team. They detect text regions using improved Rotation Region Proposal Networks. After that they extract features from text lines and employ multiple LSTM-based models to generate different results for each image. Finally, they select the one with the maximum probability among all candidate results. Please refer to the paper entiled "AdaDNNs: Adaptive Ensemble of Deep Neural Networks for Scene Text Recognition", arXiv, 2017.
