Class ImageMotionPtkSmartRespawn<I extends ImageBase,IT extends InvertibleTransform>

java.lang.Object

boofcv.alg.sfm.d2.ImageMotionPtkSmartRespawn<I,IT>

public class ImageMotionPtkSmartRespawn<I extends ImageBase,IT extends InvertibleTransform>
extends java.lang.Object

Examines tracks inside of ImageMotionPointTrackerKey and decides when new feature tracks should be respawned. Tracks are respawned when an absolute minimum is reached, when the number of inliers has dropped past a certain threshold, and when the area covered by the inliers decreases by too much. Prunes clusters of closely packed points. These tend to be non-informative and use up computational resources.

Constructor Detail

ImageMotionPtkSmartRespawn

public ImageMotionPtkSmartRespawn(ImageMotionPointTrackerKey<I,IT> motion,
                                  int absoluteMinimumTracks,
                                  double relativeInlierFraction,
                                  double respawnCoverageFraction)

Specifies internal algorithms and reset parameters.

Parameters:

motion - Algorithm for estimating image motion

absoluteMinimumTracks - Create new key-frame if number of inliers drops below this number

relativeInlierFraction - Create new key-frame if ratio of inliers to the original count drops below this number

respawnCoverageFraction - Create new key-frame if ratio point area coverage below this number
