The `opencv` image processing platform allows you to create a standalone image processor without the linked camera entity as mentioned in the [OpenCV page](https://home-assistant.io/components/opencv).
[OpenCV](http://www.opencv.org) is an open source computer vision image and video processing library.
Please refer to the [component](/components/opencv/) configuration on how to setup the image processor.
Some pre-defined classifiers can be found here: https://github.com/opencv/opencv/tree/master/data
### {% linkable_title Configuration %}
To setup OpenCV with Home Assistant, add the following section to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
image_processing:
- platform: opencv
name: Front Door Faces
source:
- entity_id: camera.front_door
classifier:
mom: /path/to/classifier.xml
```
- **name** (*Required*): The name of the OpenCV image processor.
- **source** array (*Required*): List of image sources.
- **entity_id** (*Required*): A camera entity id to get picture from.
- **name** (*Optional*): This parameter allows you to override the name of your `image_processing` entity.
- **classifier** (*Optional*): Dictionary of name to path to the classifier xml file. If this field is not provided, a face classifier will be downloaded from OpenCV's github repo.
**classifier** may also be defined as a dictionary of names to classifier configurations:
```yaml
mom:
file: /path/to/classifier/xml
neighbors: 4
min_size: (40, 40)
scale: 1.1f
```
- **file** (*Required*): The path to the classifier xml file.
- **scale** (*Optional*): The scale to perform when processing, this is a `float` value that must be greater than or equal to `1.0`, default is `1.1`.
- **neighbors** (*Optional*): The minimum number of neighbors required for a match, default is `4`. The higher this number, the more picky the matching will be; lower the number, the more false positives you may experience.

### {% linkable_title Configuration %}
To setup OpenCV with Home Assistant, add the following section to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
opencv:
classifier_group:
- name: Family
add_camera: True
entity_id:
- camera.front_door
- camera.living_room
classifier:
- file_path: /path/to/classifier/face.xml
name: Bob
- file_path: /path/to/classifier/face_profile.xml
name: Jill
min_size: (20, 20)
color: (255, 0, 0)
scale: 1.6
neighbors: 5
- file_path: /path/to/classifier/kid_face.xml
name: Little Jimmy
```
Configuration variables:
- **name** (*Required*): The name of the OpenCV image processor.
- **entity_id** (*Required*): The camera entity or list of camera entities that this classification group will be applied to.
- **classifier** (*Required*): The classification configuration for to be applied:
- **file_path** (*Required*): The path to the HAARS or LBP classification file (xml).
- **name** (*Optional*): The classification name, the default is `Face`.
- **min_size** (*Optional*): The minimum size for detection as a tuple `(width, height)`, the default is `(30, 30)`.
- **color** (*Optional*): The color, as a tuple `(Blue, Green, Red)` to draw the rectangle when linked to a dispatcher camera, the default is `(255, 255, 0)`.
- **scale** (*Optional*): The scale to perform when processing, this is a `float` value that must be greater than or equal to `1.0`, default is `1.1`.
- **neighbors** (*Optional*): The minimum number of neighbors required for a match, default is `4`. The higher this number, the more picky the matching will be; lower the number, the more false positives you may experience.
Once OpenCV is configured, it will create an `image_processing` entity for each classification group/camera entity combination as well as a camera so you can see what Home Assistant sees.
The attributes on the `image_processing` entity will be:
```json
'matches': {
'Bob': [
(x, y, w, h)
],
'Jill': [
(x, y, w, h)
],
'Little Jimmy': [
(x, y, w, h)
]
}
```
