Reference implementation of CTPN (Connectionist Text Proposal Network) for detecting text lines in natural images, from the ECCV 2016 paper. It ships with a trained Caffe model and demo scripts for scene text detection.

Use cases

• detect text regions in natural scene images
• run scene text detection with a pretrained model
• locate text lines in photos before OCR
• reproduce CTPN results from the ECCV 2016 paper
• benchmark text detection models

When to choose

• you need the original CTPN implementation for research or paper reproduction
• you work with Caffe and legacy Python 2.7 deep learning stacks
• you want a pretrained scene text detector to study or extend

When to avoid

• you need a maintained, production-ready text detector
• you use modern frameworks like PyTorch or TensorFlow
• you cannot build legacy Caffe with CUDA 7.0 and Python 2.7
• you need side-refinement or end-to-end OCR
