# continueTracking(at:sourceImage:sourceDisparity:)

An object that continues to track an object that you’ve started tracking, and adds a new detection to the detection track you’re building.

```
func continueTracking(at time: CMTime, sourceImage: CVPixelBuffer, sourceDisparity: CVPixelBuffer) -> CNBoundsPrediction?
```

## 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

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