# Requirements
Before using our SDK make sure you have installed CompreFace and Python on your machine.
1. [CompreFace](https://github.com/exadel-inc/CompreFace#getting-started-with-compreface)
2. [Python](https://www.python.org/downloads/) (Version 3.7+)
## CompreFace compatibility matrix
| CompreFace Python SDK version | CompreFace 0.5.x | CompreFace 0.6.x |
| ------------------------------| ---------------- | ---------------- |
| 0.1.0 | ✔ | :yellow_circle: |
| 0.6.x | :yellow_circle: | ✔ |
Explanation:
* ✔ SDK supports all functionality from CompreFace.
* :yellow_circle: SDK works with this CompreFace version.
In case if CompreFace version is newer - SDK won't support new features of CompreFace. In case if CompreFace version is older - new SDK features will fail.
* ✘ There are major backward compatibility issues. It is not recommended to use these versions together
# Installation
It can be installed through pip:
```shell
pip install compreface-sdk
```
# Usage
All these examples you can find in repository inside [examples](/examples) folder.
## Initialization
To start using Python SDK you need to import `CompreFace` object from 'compreface-sdk' dependency.
Then you need to init it with `url` and `port`. By default, if you run CompreFace on your local machine, it's `http://localhost` and `8000` respectively.
You can pass optional `options` object when call method to set default parameters, see reference for [more information](#options-structure).
After you initialized `CompreFace` object you need to init the service object with the `api key` of your face service. You can use this service object to recognize faces.
However, before recognizing you need first to add faces into the face collection. To do this, get the face collection object from the service object.
```python
from compreface import CompreFace
from compreface.service import RecognitionService
from compreface.collections import FaceCollection
from compreface.collections.face_collections import Subjects
DOMAIN: str = 'http://localhost'
PORT: str = '8000'
API_KEY: str = 'your_face_recognition_key'
compre_face: CompreFace = CompreFace(DOMAIN, PORT)
recognition: RecognitionService = compre_face.init_face_recognition(API_KEY)
face_collection: FaceCollection = recognition.get_face_collection()
subjects: Subjects = recognition.get_subjects()
```
## Adding faces into a face collection
Here is example that shows how to add an image to your face collection from your file system:
```python
image_path: str = 'examples/common/jonathan-petit-unsplash.jpg'
subject: str = 'Jonathan Petit'
face_collection.add(image_path=image_path, subject=subject)
```
## Recognition
This code snippet shows how to recognize unknown face.
```python
image_path: str = 'examples/common/jonathan-petit-unsplash.jpg'
recognition.recognize(image_path=image_path)
```
## Webcam demo
Webcam demo shows how to use CompreFace Recognition and Detection services using Python SDK.
In both cases, age, gender and mask plugins are applied.
Follow this [link](/webcam_demo) to see the instructions.
# Reference
## CompreFace Global Object
Global CompreFace Object is used for initializing connection to CompreFace and setting default values for options.
Default values will be used in every service method if applicable.
If the option’s value is set in the global object and passed as a function argument then the function argument value will be used.
**Constructor:**
```CompreFace(domain, port, options)```
| Argument | Type | Required | Notes |
| ---------| ------ | -------- | ----------------------------------------- |
| url | string | required | URL with protocol where CompreFace is located. E.g. `http://localhost` |
| port | string | required | CompreFace port. E.g. `8000` |
| options | object | optional | Default values for face recognition services. See more [here](#options-structure). `AllOptionsDict` object can be used in this method |
Possible options:
| Option | Type | Notes |
| --------------------| ------ | ----------------------------------------- |
| det_prob_threshold | string | minimum required confidence that a recognized face is actually a face. Value is between 0.0 and 1.0 |
| limit | integer | maximum number of faces on the image to be recognized. It recognizes the biggest faces first. Value of 0 represents no limit. Default value: 0 |
| prediction_count | integer | maximum number of subject predictions per face. It returns the most similar subjects. Default value: 1 |
| face_plugins | string | comma-separated slugs of face plugins. If empty, no additional information is returned. [Learn more](https://github.com/exadel-inc/CompreFace/tree/master/docs/Face-services-and-plugins.md) |
| status | boolean | if true includes system information like execution_time and plugin_version fields. Default value is false |
Example:
```python
from compreface import CompreFace
DOMAIN: str = 'http://localhost'
PORT: str = '8000'
compre_face: CompreFace = CompreFace(domain=DOMAIN, port=PORT, options={
"limit": 0,
"det_prob_threshold": 0.8,
"prediction_count": 1,
"face_plugins": "calculator,age,gender,landmarks",
"status": "true"
})
```
### Methods

```
## Options structure
Options is optional field in every request that contains an image.
If the option’s value is set in the global object and passed as a function argument then the function argument value will be used.
```python
class DetProbOptionsDict(TypedDict):
det_prob_threshold: float
class ExpandedOptionsDict(DetProbOptionsDict):
limit: int
status: bool
face_plugins: str
class AllOptionsDict(ExpandedOptionsDict):
prediction_count: int
```
| Option | Type | Notes |
| --------------------| ------ | ----------------------------------------- |
| det_prob_threshold | string | minimum required confidence that a recognized face is actually a face. Value is between 0.0 and 1.0 |
| limit | integer | maximum number of faces on the image to be recognized. It recognizes the biggest faces first. Value of 0 represents no limit. Default value: 0 |
| prediction_count | integer | maximum number of subject predictions per face. It returns the most similar subjects. Default value: 1 |

Example of face recognition with object:
```python
recognition.recognize(image_path=image_path, options={
"limit": 0,
"det_prob_threshold": 0.8,
"prediction_count": 1,
"face_plugins": "calculator,age,gender,landmarks",
"status": "true"
})
```
## Face Recognition Service
Face recognition service is used for face identification.
This means that you first need to upload known faces to face collection and then recognize unknown faces among them.
When you upload an unknown face, the service returns the most similar faces to it.
Also, face recognition service supports verify endpoint to check if this person from face collection is the correct one.

## Face Verification Service
*[Example](examples/verify_face_from_image.py)*
Face verification service is used for comparing two images.
A source image should contain only one face which will be compared to all faces on the target image.
**Methods:**
### Verify
```python
verify.verify(source_image_path, target_image_path, options)
```
Compares two images provided in arguments. Source image should contain only one face, it will be compared to all faces in the target image.
| Argument | Type | Required | Notes |
| ------------------ | ------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| image_id | UUID | required | UUID of the verifying face |
| source_image_path | image | required | file to be verified. Image can pass from url, local path or bytes. Max size is 5Mb |
| target_image_path | image | required | reference file to check the source file. Image can pass from url, local path or bytes. Max size is 5Mb |
| options | string | Object | `ExpandedOptionsDict` object can be used in this method. See more [here](#options-structure). |
