PlToGrayMotion2D

public PlToGrayMotion2D(ImageMotion2D<T,IT> motion,
 Class<T> imageType)

Method Details

process

public boolean process(Planar<T> input)

Description copied from interface: ImageMotion2D

Processes and updates the image transform. The very first image processed will always return true and have a transform of no motion.

Specified by:

process in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

Parameters:

input - Next image in the sequence. Not modified.

Returns:

true if the transform has been updated and false if not

reset

public void reset()

Description copied from interface: ImageMotion2D

Resets the class into its initial state and throws away any information on the image sequence

Specified by:

reset in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

setToFirst

public void setToFirst()

Description copied from interface: ImageMotion2D

Turns the current image into the origin of the coordinate system.

Specified by:

setToFirst in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

getFrameID

public long getFrameID()

Description copied from interface: ImageMotion2D

Returns the ID of the most recently processed frame. Starts at zero and increments with each call to process.

Specified by:

getFrameID in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

getFirstToCurrent

public IT getFirstToCurrent()

Description copied from interface: ImageMotion2D

Transform from first image into the current image. NOTE: Returned transform is owned by this class and can be modified after any function is called.

Specified by:

getFirstToCurrent in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

Returns:

Image transform

getTransformType

public Class<IT> getTransformType()

Description copied from interface: ImageMotion2D

Type of transform that it estimates

Specified by:

getTransformType in interface ImageMotion2D<T extends ImageGray<T>,IT extends InvertibleTransform<IT>>

Returns:

Transform type.

getTotalTracks

public int getTotalTracks()

Description copied from interface: AccessPointTracks

Returns the total number of tracks

Specified by:

getTotalTracks in interface AccessPointTracks

getTrackId

public long getTrackId(int index)

Description copied from interface: AccessPointTracks

Used to get the track ID of an active Track

Specified by:

getTrackId in interface AccessPointTracks

Parameters:

index - which track

Returns:

The track's ID

getTrackPixel

public void getTrackPixel(int index,
 Point2D_F64 pixel)

Description copied from interface: AccessPointTracks

Gets the observed coordinate of a feature in the input image.

Specified by:

getTrackPixel in interface AccessPointTracks

Parameters:

index - Which point in the list

pixel - Where the coordinate will be writen to.

getAllTracks

public List<Point2D_F64> getAllTracks(@Nullable
 @Nullable List<Point2D_F64> storage)

Description copied from interface: AccessPointTracks

All the points being actively tracked in pixel coordinates.

Specified by:

getAllTracks in interface AccessPointTracks

Returns:

all active tracks in pixel coordinates

isTrackInlier

public boolean isTrackInlier(int index)

Description copied from interface: AccessPointTracks

True if the specified track is an inlier used in motion estimation

Specified by:

isTrackInlier in interface AccessPointTracks

Parameters:

index - The index in all

Returns:

if it is an inlier or not

isTrackNew

public boolean isTrackNew(int index)

Description copied from interface: AccessPointTracks

True if the specified track was just spawned

Specified by:
