  # LiteALPR Models
13
 
14
- Pretrained weights for **LiteALPR**, an ultra-fast, open-source Automatic License Plate Recognition (ALPR) library explicitly optimized for high-throughput execution.
15
 
16
  ## Model Details
17
  - **Architecture**:
18
  - **Detector**: YOLOv8n-Efficient (utilizing Ghost Convolution via lightweight C3Ghost blocks).
19
- - **Recognizer**: SVTR26-Tiny (featuring an Efficient RCTC Decoder to bypass heavy attention mechanisms).
20
  - **License**: GNU Affero General Public License v3.0 (AGPL-3.0)
 
21
 
22
  ## Training Data
23
- The models were trained and validated on a large-scale aggregated dataset of 52,595 images, encompassing:
24
- - **Brazil**: RodoSol-ALPR dataset.
25
- - **China**: CBLPRD dataset.
26
- - **Vietnam**: Public datasets and self-collected real-world traffic footage.
27
 
28
- Half of the recognition crops were synthetically degraded (motion blur, Gaussian noise, perspective skew) to ensure high robustness in real-world scenarios.
29
 
30
  ## Evaluation Results
31
  - **Detection (YOLOv8n-Efficient)**: 99.45% mAP@50, 5.69 GFLOPs, 2.00M parameters.
32
  - **Recognition (SVTR26-Tiny)**: 89.15% Sequence Accuracy, 3.28% Character Error Rate (CER), 4.22M parameters.
33
-
34
- *Note: Tested on NVIDIA RTX 3060 and AMD Ryzen 5 CPU in ONNX FP32 format.*
35
 
36
  ## Known Limitations
37
- - The model is currently optimized and validated specifically for license plates from **Vietnam, Brazil, and China**. Recognition accuracy may degrade for other regional formats without fine-tuning.

  # LiteALPR Models
13
 
14
+ Pretrained weights for **LiteALPR**, a lightweight open-source library for fast and accurate Automatic License Plate Recognition (ALPR), explicitly optimized for high-throughput execution on both edge and cloud environments.
15
 
16
  ## Model Details
17
  - **Architecture**:
18
  - **Detector**: YOLOv8n-Efficient (utilizing Ghost Convolution via lightweight C3Ghost blocks).
19
+ - **Recognizer**: SVTR26-Tiny (featuring an Efficient RCTC Decoder to bypass computationally heavy attention mechanisms).
20
  - **License**: GNU Affero General Public License v3.0 (AGPL-3.0)
21
+ - **Repository**: [LiteALPR GitHub](https://github.com/vn-anhnth/LiteALPR)
22
 
23
  ## Training Data
24
+ To ensure robust, multi-national generalization, the models were trained and validated on a large-scale aggregated dataset of 52,595 images from diverse geographic regions:
25
+ - **Brazil**: [RodoSol-ALPR Dataset](https://github.com/laroca/RodoSol-ALPR)
26
+ - **China**: [CBLPRD Dataset](https://github.com/detectRecog/CBLPRD)
27
+ - **Vietnam**: [Kaggle License Plates Dataset](https://www.kaggle.com/datasets/duydieunguyen/licenseplates) alongside proprietary self-collected real-world traffic footage.
28
 
29
+ Half of the recognition crops were synthetically degraded (e.g., motion blur, Gaussian noise, perspective skew) during training to ensure high resilience against challenging real-world scenarios.

31
  ## Evaluation Results
32
  - **Detection (YOLOv8n-Efficient)**: 99.45% mAP@50, 5.69 GFLOPs, 2.00M parameters.
33
  - **Recognition (SVTR26-Tiny)**: 89.15% Sequence Accuracy, 3.28% Character Error Rate (CER), 4.22M parameters.
34
+ - **End-to-End Speed**: 66.5 FPS on GPU (NVIDIA RTX 3060) and 23.4 FPS on CPU (AMD Ryzen 5 4600G) using ONNX FP32 execution.
 
35
 
36
  ## Known Limitations
37
+ - The model currently provides highly accurate out-of-the-box support for **single-line alphanumeric license plates** (A–Z, Đ, 0–9) typical of many global regions.
38
+ - Recognition accuracy on heavily curved multi-line plates or non-Latin characters (e.g., Cyrillic, Arabic) may require custom fine-tuning using the provided training scripts.
