# Camel OpenIMAJ component

Camel OpenIMAJ component can be used to detect faces in images. Camel OpenIMAJ component supports only producer endpoints.

## Maven dependency

Maven users should add the following dependency to their POM file:

io.rhiotcamel-openimag${rhiot.version}

Avaliable for rhiot.version >= 0.1.3

## URI format

```
openimaj:label
```

Where `label` can be replaced with any text label:

```
from("webcam:spycam").to("openimaj:face-detection");
```

This routes the input stream from the webcam to the openimaj component, when a face is detected the resulting body will be an instance of org.openimaj.image.processing.face.detection.DetectedFace, and List when there are multiple faces.

The component uses a face detector based on the Haar cascade by default, optionally set an alternate detector;

```
from("webcam:spycam").to("openimaj:face-detection?faceDetector=#anotherDetector");
```

Using the ProducerTemplate, the following example uses the FKEFaceDetector which is a wrapper around the Haar detector, providing additional information by finding facial keypoints on top of the face;

```
KEDetectedFace face = template.requestBody("openimaj:face-detection?faceDetector=#fkeFaceDetector", inputStream, KEDetectedFace.class);
FacialKeypoint keypoint = face.getKeypoint(FacialKeypoint.FacialKeypointType.EYE_LEFT_LEFT);
```

The confidence in the face detection is set to the low default of 1, you can set the minimum confidence threshold on the endpoint;

```
from("webcam:spycam").to("openimaj:face-detection?confidence=50");
```

### URI Options Parameters

| Option         | Default value               | Description                                                                                      |
| -------------- | --------------------------- | ------------------------------------------------------------------------------------------------ |
| `faceDetector` | `new HaarCascadeDetector()` | \`org.openimaj.image.processing.face.detection.HaarCascadeDetector' is the default face detector |
| `confidence`   | 1                           | The minimum confidence of the detection; higher numbers mean higher confidence.                  |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://rhiot.gitbook.io/rhiotdocumentation/index-1/index/camel_openimaj_component.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
