I recently discovered the stroke width transform, as documented in the following research paper:
- Detecting Text in Natural Scenes with Stroke Width Transform. Boris Epshtein, Yonathan Wexler, and Eyal Ofek. IEEE International Conference on Computer Vision and Pattern Recognition, 2010.
The algorithm is intended for detecting and extracting text from natural scenes.
However, I could not find any implementation, and from the paper I find it hard to determine all the details regarding the algorithm so I can implement it in practice. Does anyone know if this algorithm is implemented and used in practice in a system? Is there a C# or Java implementation of it?
My friend Andrew and I implemented Stoke Width Transform (SWT) on a mobile phone during a class project at Cornell. Maybe you can get hint from the report.
