PointTrackerToTwoPass (boofcv-geo 0.29 API)

java.lang.Object
- boofcv.abst.feature.tracker.PointTrackerToTwoPass<T>

All Implemented Interfaces:

PointTracker<T>, PointTrackerTwoPass<T>
```
public class PointTrackerToTwoPass<T extends boofcv.struct.image.ImageBase<T>>
extends java.lang.Object
implements PointTrackerTwoPass<T>
```
Wrapper class that allows PointTracker to be used as a PointTrackerTwoPass. Since PointTrack does not have all the same capabilities of PointTrackerTwoPass not all operations are supported or behave in exactly the same way. Use of this interface is only appropriate when a two pass tracker is being used as a regular point tracker.

  - process
```
public void process(T image)
```
    Description copied from interface: PointTrackerTwoPass
    
    Changes behavior of PointTracker.process(boofcv.struct.image.ImageBase) in that it will only update each track's location, but not its description, and the active list. Call PointTrackerTwoPass.finishTracking() to update the track's description, the inactive list, and the dropped list. An exception is thrown if multiple calls to this function are made without calling PointTrackerTwoPass.finishTracking().

    process in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
    
    Specified by:
    
    process in interface PointTrackerTwoPass<T extends boofcv.struct.image.ImageBase<T>>
    
    Parameters:
    
    image - Next image in the sequence
  - reset
```
public void reset()
```
    Description copied from interface: PointTracker
    
    Discard memory of all current and past tracks. Growing buffered might not be reset to their initial size by this method.
    
    Specified by:
    
    reset in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
  - dropAllTracks
```
public void dropAllTracks()
```
    Description copied from interface: PointTracker
    
    Drops all feature to be dropped and will no longer be tracked. Tracks dropped using this function will not appear in the dropped list.
    
    Specified by:
    
    dropAllTracks in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
  - dropTrack
```
public boolean dropTrack(PointTrack track)
```
    Description copied from interface: PointTracker
    
    Manually forces a track to be dropped. Tracks dropped using this function will not appear in the dropped list and their data is subject to being immediately recycled. New requests to all and active lists will not include the track after it has been dropped using this function. If request is made to drop a track that is not being tracked (in the internal all list), then the request is ignored.
    
    Specified by:
    
    dropTrack in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
    
    Parameters:
    
    track - The track which is to be dropped
    
    Returns:
    
    true if the request to drop the track was done or if it was ignored because the track wasn't being tracked
  - getAllTracks
```
public java.util.List<PointTrack> getAllTracks(java.util.List<PointTrack> list)
```
    Description copied from interface: PointTracker

    getAllTracks in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
    
    Parameters:
    
    list - Optional storage for the list of tracks. If null a new list will be declared internally.
    
    Returns:
    
    List of tracks.
  - getActiveTracks
```
public java.util.List<PointTrack> getActiveTracks(java.util.List<PointTrack> list)

    Description copied from interface: PointTracker
    
    Returns a list of active tracks. An active track is defined as a track which was found in the most recently processed image.

    getActiveTracks in interface PointTracker<T extends boofcv.struct.image.ImageBase<T>>
