Uses of PointFloat in net.grelf.grip

Fields in net.grelf.grip declared as PointFloat

PointFloat

BlobMeas.centre Centre of gravity of the blob as initially detected.

Methods in net.grelf.grip that return PointFloat

PointFloat	Blob.densityCentre(java.awt.image.BufferedImage im) Calculate centre of the blob with weighting from pixel densities (brightnesses).
PointFloat	Blob_.densityCentre(java.awt.image.BufferedImage im) Calculate the centre of the blob with weighting from pixel densities (brightnesses).
PointFloat	Blob.maskCentre() Calculate centre of the blob simply as average of detected x and y, with no weighting from pixel densities.
PointFloat	Blob_.maskCentre() Calculate the centre of the blob simply as average of detected x and y, with no weighting from pixel densities.

Methods in net.grelf.grip that return types with arguments of type PointFloat

java.util.List<PointFloat>	Blob_.getVerticalCentreLineFromBoundary() Get a list of the centre points of all horizontal rows that comprise the blob with a simple shape.
java.util.List<PointFloat>	Blob.getVerticalCentreLineFromRegion() Get a list of the centre points of all horizontal rows that comprise the blob.
java.util.List<PointFloat>	Blob_.getVerticalCentreLineFromRegion() Get a list of the centre points of all horizontal rows that comprise the blob.

Methods in net.grelf.grip with parameters of type PointFloat

void	StarMeasProcessor.addPoint(PointFloat pt)
protected void	CometProcessor.process(PointFloat cometCentre, java.awt.image.BufferedImage bim) Called when each CometFrame closes - not for use otherwise.
void	CometFrame.setCometCentre(PointFloat pt)
static void	Warp.warp(java.awt.image.BufferedImage imOld, PointFloat[] oldPts, java.awt.image.BufferedImage imNew, PointFloat[] newPts) Warp imOld into separate image imNew, using second order polynomials.
static void	Warp.warp(java.awt.image.BufferedImage imOld, PointFloat[] oldPts, java.awt.image.BufferedImage imNew, PointFloat[] newPts) Warp imOld into separate image imNew, using second order polynomials.
static void	Warp.warp(Image imageOld, PointFloat[] oldPts, Image imageNew, PointFloat[] newPts) Warp imOld into separate image imNew, using second order polynomials.

Method parameters in net.grelf.grip with type arguments of type PointFloat

boolean	Accumulator.brightestShiftAccumulate(Image8or16Base image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. 9.11.26: changed last parameter from BlobMeas [][] lookup.
boolean	Accumulator32.brightestShiftAccumulate(Image8or16Base image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. NB: Does NOT set this.extremes, so must call getOverallRange () at end of sequence. 9.11.26: changed last parameter from BlobMeas [][] lookup.
boolean	Accumulator64.brightestShiftAccumulate(Image8or16Base image, int imNo, int middleImNo, java.util.List<PointFloat> centres) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that brightest objects in this image and the middle image of the sequence are superimposed. 9.11.26: changed last parameter from BlobMeas [][] lookup.
