Converting Opensourced OCR Models to TFLite

This repository is to create tflite models for the available ocr models.

TFLite Models Available

Note: Currently Keras OCR doesn't support Integer Quantization as of now and already reported to TFLite team.

                                       All the above benchmarks are w.r.t Redmi K20 Pro using 4threads.

Tensorflow Hub

Keras OCR Models are published in TensorFlow Hub

You can find this repo for converting CRAFT models to TFLite and using them for inference. For more details please find these blogs on Text Detectors.

Feel free to suggest any other models through issues or contribute through Pull Requests.
