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.
