# InsightFace Python Library
|
|
|
|
## License
|
|
|
|
The code of InsightFace Python Library is released under the MIT License. There is no limitation for both academic and commercial usage.
|
|
|
|
**The pretrained models we provided with this library are available for non-commercial research purposes only, including both auto-downloading models and manual-downloading models.**
|
|
|
|
## Install
|
|
|
|
### Install Inference Backend
|
|
|
|
For ``insightface<=0.1.5``, we use MXNet as inference backend.
|
|
|
|
Starting from insightface>=0.2, we use onnxruntime as inference backend.
|
|
|
|
You have to install ``onnxruntime-gpu`` manually to enable GPU inference, or install ``onnxruntime`` to use CPU only inference.
|
|
|
|
## Change Log
|
|
|
|
### [0.6] - 2022-01-29
|
|
|
|
#### Added
|
|
|
|
- Add pose estimation in face-analysis app.
|
|
|
|
#### Changed
|
|
|
|
- Change model automated downloading url, to ucloud.
|
|
|
|
|
|
## Quick Example
|
|
|
|
```
|
|
import cv2
|
|
import numpy as np
|
|
import insightface
|
|
from insightface.app import FaceAnalysis
|
|
from insightface.data import get_image as ins_get_image
|
|
|
|
app = FaceAnalysis(providers=['CUDAExecutionProvider', 'CPUExecutionProvider'])
|
|
app.prepare(ctx_id=0, det_size=(640, 640))
|
|
img = ins_get_image('t1')
|
|
faces = app.get(img)
|
|
rimg = app.draw_on(img, faces)
|
|
cv2.imwrite("./t1_output.jpg", rimg)
|
|
```
|
|
|
|
This quick example will detect faces from the ``t1.jpg`` image and draw detection results on it.
|
|
|
|
|
|
|
|
## Model Zoo
|
|
|
|
In the latest version of insightface library, we provide following model packs:
|
|
|
|
Name in **bold** is the default model pack. **Auto** means we can download the model pack through the python library directly.
|

|
|
|
|
*buffalo_m has the same accuracy with buffalo_l.*
|
|
|
|
*buffalo_sc has the same accuracy with buffalo_s.*

|
|
|
|
**Note that these models are available for non-commercial research purposes only.**
|
|
|
|
|
|
|
|
For insightface>=0.3.3, models will be downloaded automatically once we init ``app = FaceAnalysis()`` instance.
|
|
|
|
For insightface==0.3.2, you must first download the model package by command:
|
|
|
|
```
|
|
insightface-cli model.download antelope
|
|
```
|
|
or
|
|
```
|
|
insightface-cli model.download antelopev2
|
|
```
|
|
|
|
## Use Your Own Licensed Model
|
|
|
|
You can simply create a new model directory under ``~/.insightface/models/`` and replace the pretrained models we provide with your own models. And then call ``app = FaceAnalysis(name='your_model_zoo')`` to load these models.
|
|
|
|
## Call Models
|
|
|
|
The latest insightface libary only supports onnx models. Once you have trained detection or recognition models by PyTorch, MXNet or any other frameworks, you can convert it to the onnx format and then they can be called with insightface library.
|
|
|
|
### Call Detection Models
|
|
|
|
```
|
|
import cv2
|
|
import numpy as np
|
|
import insightface
|
|
from insightface.app import FaceAnalysis
|
|
from insightface.data import get_image as ins_get_image
|
|
|
|
# Method-1, use FaceAnalysis
|
|
app = FaceAnalysis(allowed_modules=['detection']) # enable detection model only
|
|
app.prepare(ctx_id=0, det_size=(640, 640))
|
|
|
|
# Method-2, load model directly
|
|
detector = insightface.model_zoo.get_model('your_detection_model.onnx')
|
|
detector.prepare(ctx_id=0, input_size=(640, 640))
|
|
|
|
```
|
|
|
|
### Call Recognition Models
|
|
|
|
```
|
|
import cv2
|
|
import numpy as np
|
|
import insightface
|
|
from insightface.app import FaceAnalysis
|
|
from insightface.data import get_image as ins_get_image
|
|
|
|
handler = insightface.model_zoo.get_model('your_recognition_model.onnx')
|
|
handler.prepare(ctx_id=0)
|
|
|
|
```
