OCR Tamil can help you extract text from signboard, nameplates, storefronts etc., from Natural Scenes with high accuracy. This version of OCR is much more robust to tilted text compared to the Tesseract, Paddle OCR and Easy OCR as they are primarily built to work on the documents texts and not on natural scenes. This model is work in progress, feel free to contribute!!!

## How to Install and Use OCR Tamil 👨🏼💻
### Quick links🌐
📔 Detailed explanation on [Medium article](https://gnana70.medium.com/ocr-tamil-easy-accurate-and-simple-to-use-tamil-ocr-b03b98697f7b).
✍️ Experiment in [Colab notebook](https://colab.research.google.com/drive/11QPPj3EmpoIqnpuIznKeP1icxvVOjfux?usp=sharing)
🤗 Test it in [Huggingface spaces](https://huggingface.co/spaces/GnanaPrasath/ocr_tamil)
### Pip install instructions🐍
In your command line, run the following command ```pip install ocr_tamil```
If you are using jupyter notebook , install like ```!pip install ocr_tamil```
### Python Usage - Single image inference
**Text Recognition only**
```python
from ocr_tamil.ocr import OCR
image_path = r"test_images\1.jpg" # insert your own path here
ocr = OCR()
text_list = ocr.predict(image_path)
print(text_list[0])
## OUTPUT : நெடுஞ்சாலைத்
```
<img width="200" alt="teaser" src="https://github.com/gnana70/tamil_ocr/raw/main/test_images/1_180.jpg">
**Text Detect + Recognition**
```python
from ocr_tamil.ocr import OCR
image_path = r"test_images\0.jpg" # insert your own image path here
ocr = OCR(detect=True)
texts = ocr.predict(image_path)
print(" ".join(text_list[0]))
## OUTPUT : கொடைக்கானல் Kodaikanal
```
<img width="400" alt="teaser" src="https://github.com/gnana70/tamil_ocr/raw/main/test_images/0.jpg">
### Batch inference mode 💻
**Text Recognition only**
```python
from ocr_tamil.ocr import OCR
image_path = [r"test_images\1.jpg",r"test_images\2.jpg"] # insert your own image paths here
ocr = OCR()
text_list = ocr.predict(image_path)
for text in text_list:
print(text)
## OUTPUT : நெடுஞ்சாலைத்
## OUTPUT : கோபி
```
**Text Detect + Recognition**
```python
from ocr_tamil.ocr import OCR
image_path = [r"test_images\0.jpg",r"test_images\tamil_sentence.jpg"] # insert your own image paths here
ocr = OCR(detect=True)
text_list = ocr.predict(image_path)
for item in text_list:
print(" ".join(item))
## OUTPUT : கொடைக்கானல் Kodaikanal
## OUTPUT : செரியர் யற்கை மூலிகைகளில் இருந்து ஈர்த்தெடுக்க்கப்பட்ட வீரிய உட்பொருட்களை உள்ளடக்கி எந்த இரசாயன சேர்க்கைகளும் இல்லாமல் உருவாக்கப்பட்ட இந்தியாவின் முதல் சித்த தயாரிப்பு
```
### Advanced usage🚀
OCR module can be initialized by setting following parameters as per your requirements
```
1. Confidence of word -> OCR(details=1)
2. Bounding Box and Confidence of word -> OCR(detect=True,details=2)
3. To change the CRAFT Text detection settings -> OCR(detect=True,text_threshold=0.5,
link_threshold=0.1,
low_text=0.30)
4. To increase the Batch size of text recognition -> OCR(batch_size=16) # set as per available memory
5. To configure the language to be extracted -> OCR(lang=["tamil"]) # list can take "english" or "tamil" or both. Defaults to both language
```
**Tested using Python 3.10 on Windows & Linux (Ubuntu 22.04) Machines**
## Applications⚡
1. ADAS system navigation based on the signboards + maps (hybrid approach) 🚁
2. License plate recognition 🚘
## Limitations⛔
1. Unable to read the text if they are present in rotated forms
<p align="left">
<img width="200" alt="teaser" src="https://github.com/gnana70/tamil_ocr/raw/main/test_images/9.jpg">
<img width="200" alt="teaser" src="https://github.com/gnana70/tamil_ocr/raw/main/test_images/8.jpg">
</p>
2. Currently supports Only English and Tamil Language
3. Document Text reading capability is limited. Auto identification of Paragraph, reading order are not supported along with Text detection model inability to detect and crop the Tamil text leads to accuracy decrease (**WORKAROUND** Can use your own text detection model along with OCR tamil text recognition model)

parameters as per your requirements\r\n\r\n```\r\n1. Confidence of word -> OCR(details=1)\r\n2. Bounding Box and Confidence of word -> OCR(detect=True,details=2)\r\n3. To change the CRAFT Text detection settings -> OCR(detect=True,text_threshold=0.5,\r\n link_threshold=0.1,\r\n low_text=0.30)\r\n4. To increase the Batch size of text recognition -> OCR(batch_size=16) # set as per available memory\r\n5. To configure the language to be extracted -> OCR(lang=[\"tamil\"]) # list can take \"english\" or \"tamil\" or both. Defaults to both language\r\n```\r\n\r\n**Tested using Python 3.10 on Windows & Linux (Ubuntu 22.04) Machines**\r\n\r\n## Applications\u26a1\r\n1. ADAS system navigation based on the signboards + maps (hybrid approach) \ud83d\ude81\r\n2. License plate recognition \ud83d\ude98\r\n\r\n## Limitations\u26d4\r\n\r\n1.
