## Usage (python)

```python
from facelib import facerec
import cv2
# You can use face_detector, landmark_detector or feature_extractor individually using .predict method. e.g.(bboxes = facedetector.predict(img))
face_detector = facerec.SSDFaceDetector()
landmark_detector = facerec.LandmarkDetector()
feature_extractor = facerec.FeatureExtractor()

pipeline = facerec.Pipeline(face_detector, landmark_detector, feature_extractor)
path_img = './path_to_some_image.jpg'
img = cv2.imread(path_img)
img = img[...,::-1] # cv2 returns bgr format but every method inside this package takes rgb format
bboxes, landmarks, features = pipeline.predict(img)
# Note that values returned (bboxes and landmarks) are in fraction.[0,1]
```

## Installation

### Pip installation

```bash
pip3 install facelib
```

### TFLite runtime installation

To use facelib.facerec package use the following bash command to install tflite-runtime pip package.

```bash
python3 -m facelib --install-tflite
```

or you can install from [tensorflow.org](https://www.tensorflow.org/lite/guide/python)

### Dev package

Tensorflow is required for facelib.dev package. If you wish you can download facelib with tensorflow using the following command.

```bash
pip3 install facelib[dev]
```
