IndicPhotoOCR is a scene text recognition toolkit designed for detecting, identifying, and recognizing text across Indian languages, including Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, and English, with support for Urdu and Meitei in the pipeline. It is built to handle the unique scripts and complex structures of Indian languages, offering robust detection and recognition capabilities. The package can be installed with just few lines of code, and a straightforward wrapper function makes it easy to use.

## Installation
Currently we need to manually create virtual environemnt.
```python
conda create -n indicphotoocr python=3.9 -y
conda activate indicphotoocr


git clone https://github.com/Bhashini-IITJ/IndicPhotoOCR.git
cd IndicPhotoOCR
```
<details>
  <summary><b>CPU Installation</b></summary>

  ```bash
  python setup.py sdist bdist_wheel
  pip install dist/IndicPhotoOCR-1.3.0-py3-none-any.whl[cpu]
  ```
</details>

<details>
  <summary><b>CUDA 11.8 Installation</b></summary>

  ```bash
  python setup.py sdist bdist_wheel
  pip install ./dist/IndicPhotoOCR-1.3.0-py3-none-any.whl[cu118] --extra-index-url https://download.pytorch.org/whl/cu118
  ```
</details>

<details>
  <summary><b>CUDA 12.1 Installation</b></summary>

  ```bash
  python setup.py sdist bdist_wheel
  pip install ./dist/IndicPhotoOCR-1.3.0-py3-none-any.whl[cu121] --extra-index-url https://download.pytorch.org/whl/cu121
  ```
</details>
<br>

If you find any trouble with the above installation use the ```setup.sh``` script. Make sure you have miniconda installed.
```bash
git clone https://github.com/Bhashini-IITJ/IndicPhotoOCR.git
cd IndicPhotoOCR
chmod +x setup.sh
./setup.sh
```

## Config
Currently this model works for hindi v/s english script identification and thereby hindi and english recognition.

Detection Model: TextBPN++\
ScripIndetification Model: Hindi v/s English\
Recognition Model: Hindi, English, Assamese, Bengali, Gujarati, Marathi, Odia, Punjabi, Tamil, Telugu, Malayalam, kannada.

## How to use
### Detection

```python
>>> from IndicPhotoOCR.ocr import OCR
# Create an object of OCR
>>> ocr_system = OCR(verbose=True) # for CPU --> OCR(device="cpu")

# Get detections
>>> detections = ocr_system.detect("test_images/image_141.jpg")

# Running text detection...
# 4334 text boxes before nms
# 1.027989387512207

# Save and visualize the detection results
>>> ocr_system.visualize_detection("test_images/image_141.jpg", detections)
# Image saved at: test.png
```

### Cropped Word Script Identification
```python
>>> from IndicPhotoOCR.ocr import OCR
# Create an object of OCR
>>> ocr_system = OCR(verbose=True,  identifier_lang ="auto") # for CPU --> OCR(device="cpu")
# Get script id
>>> ocr_system.identify("test_images/cropped_image/image_141_0.jpg")
# 'hindi'
```

### Cropped Word Recognition
```python
>>> from IndicPhotoOCR.ocr import OCR
# Create an object of OCR
>>> ocr_system = OCR(verbose=True) # for CPU --> OCR(device="cpu")
# Get recognitions
>>> ocr_system.recognise("test_images/cropped_image/image_141_0.jpg", "hindi")
# Recognizing text in detected area...
# 'मण्डी'
```

### End-to-end Scene Text Recognition
```python
>>> from IndicPhotoOCR.ocr import OCR
# Create an object of OCR
>>> ocr_system = OCR(verbose=True, identifier_lang ="auto") # for CPU --> OCR(device="cpu")
# Complete pipeline
>>> ocr_system.ocr("test_images/image_141.jpg")
