Images ​

The application can receive the camera image stream from the SDK by implementing ImageListener, and then pass it to the session builder when creating a face session.

The SDK sends an ImageData object that contains:

• The current image captured by the camera.
• The face detection coordinates, as calculated by the SDK.
• The image validity information.

@override
void onImage(ImageData imageData) {
    // imageData.imageWidth -       The image's width
    // imageData.imageHeight -      The image's height
    // imageData.roi -              A geometry.Rect object
    // imageData.imageValidity -    An integer with a value from com.biosensesignal.sdk.api.images.ImageValidity class
}

By default, the SDK processes camera images in a portrait orientation, regardless of the device orientation. Instructions on how to process the camera stream in other orientations can be found at Device Orientation Setup.
