This repository is the official implementation of A Semantic-based Arbitrarily-Oriented Scene Text Detector(named STD++ as it is the improved version of STD).due to lack of computing resources and time, we tested STD++ on MTWI2018 dataset, and we hope to perform more experiments on any other benchmark datasets, such as IC15,IC17,COCO-Text,MSRA-TD500 and so on.

images come from icdar2017rctw

STD++ is the improved version of STD, which solved STD's limitations and can be used to detect arbitrarily-oriented texts, yet still preserves its accuracy and efficiency:

• no any further post-processings, like NMS.
• anchor-free.
• easy to generate training labels.
• only one step process to get final bounding boxes.

Any questions or suggestions,please drop a comment or contact me,email: [email protected].

Download RCTW17 dataset below, and configure your local directory path. refer to train.py

predict.py

We trained STD++ on MTWI2018 dataset, training and testing images can be downloaded from this site for Text Localization, and we make STD++ annotations available on baiduyun, code: nuti.
