```

## Parameters

- `time`: The presentation time of the first frame in the detection track.
- `sourceImage`: The image buffer containing the image.
- `sourceDisparity`: The disparity buffer containing depth information.

## Return Value

Return Value An object representing a prediction of where the object is in the source image.
