README
License Plate Detection with YuNet
This model is contributed by Dong Xu (徐栋) from watrix.ai (银河水滴).
Please note that the model is trained with Chinese license plates, so the detection results of other license plates with this model may be limited.
Note:
license_plate_detection_lpd_yunet_2023mar_int8bq.onnxrepresents the block-quantized version in int8 precision and is generated using block_quantize.py withblock_size=64.
