Beyond its aesthetic, the Ring code is adapted to tor geometry. It is also a real challenge of implementation.\n\n# Features\n\n## App\n\nYou can use the Streamlit app to generate your own RingCode encoded messages! Please note that the decoding module is still under development.\n\n## Requirements\n\n- python \u003e 3.6\n\n## Setup\n\n```\npython3 -m venv venv \u0026\u0026 source venv/bin/activate\npip install -r requirements.txt\nstreamlit run app.py\n```\n\n## Usage\n\nYou can play with 3 hyperparameters to change the data capacity and the shape of the barcode, in `src/encoder.py`:\n- `module_size_pixel`: the size of each tile (aka module)\n- `min_radius_pixels`: the size of the inner band of the ring, in pixel\n- `max_radius_pixels`: the size of the outer band of the ring, in pixel\n\n## Roadmap\n\nThe development of this RingCode follows the [thesis of Robin Brügger](https://www.dropbox.com/s/a62q4lotoyonnv7/P6_2015_Circular_Codes.pdf?dl=0), so hat tips to him for this impressive work.\n\nEncoding\n- [x] Create encoder\n- [x] Simple Streamlit App to display the encoding\n\nDecoding\n- [x] Barcode recognition (finding the center)\n- [ ] Find the perspective correction markers and startmarker\n- [ ] Rough perspective correction\n- [ ] Accurate perspective correction\n- [ ] Read vertical timing information\n- [ ] Evaluation of the payload modules\n- [ ] Encoding data using Reed Solomon algorithm\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvincent-maladiere%2Fringcode","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fvincent-maladiere%2Fringcode","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fvincent-maladiere%2Fringcode/lists"}
