Description: Anchor-free based detection framework with poly regression and text segmentation was used here. The model was firstly pretrained on LSVT、MLT、ReCTS，and then finetuned on ReCTS. Weighted loss was used to enhance small text instances. At testing phase, single-model-multi-scale with post-processing was used to generate the final results.

Description: Natural scene text detector(NSTD-iFLYTEK) is based on MaskRcnn with resnet-101. Only ICDAR2019 datasets are used for training, including Rects, LSVT, MLT and Art. Multi-scale training and single-scale testing are used to generate the final result, no model ensemble.
