Description: We propose a Complementary Proposal Network (CPN) that seamlessly and parallelly integrates semantic and geometric information for superior performance. This Result is achieved with single Swin-L backbone and multi-scale testing policy. No model ensemble is used.

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.
