LaserTrackerGreen (streams-video 0.1.0 API)

java.lang.Object
- stream.AbstractProcessor
- - stream.image.AbstractImageProcessor
  - - stream.laser.LaserTrackerGreen

All Implemented Interfaces:

stream.Processor, stream.StatefulProcessor
```
public class LaserTrackerGreen
extends AbstractImageProcessor
```
This processor provides a very simple strategy for detecting laser pointers in an image. It simply looks for small, very bright areas. If the laserImage property is set, a track of the identified laser-points is produced.
