Constructor and Description
Accumulator32(java.awt.image.BufferedImage bim) Use the BufferedImage to set the width, height and number of bands (channels) in this Image.
Accumulator32(Image im) Use the Image to set the width, height and number of bands (channels) in this Accumulator.
Accumulator32(int width, int height, int nBands) Creates image without setting any pixels.
Accumulator32(int width, int height, int nBands, boolean fillWithZeroes) Creates image with pixels optionally set to zero.

Method Summary

Modifier and Type	Method and Description
void	addWithStarBoost(Image image, int starBoostFactor) For accumulating star trails.
boolean	averageShiftAccumulate(Image image, int imNo, int middleImNo, java.util.List<MatchPair> matches, BlobMeas[][] lookup, int nBrightest) For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that matched point pairs are superimposed.
boolean	brightestShiftAccumulate(Image 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	warpAccumulate(Image image, int imNo, int middleImNo, java.util.List<MatchPair> matches, BlobMeas[][] lookup, int nBrightest) For image imNo of a sequence, add the pixel values into the accumulator but first distort the image so that matched point pairs are superimposed.

Constructor Detail

Accumulator32

public Accumulator32(int width,
                     int height,
                     int nBands)

Creates image without setting any pixels.

Accumulator32

public Accumulator32(int width,
                     int height,
                     int nBands,
                     boolean fillWithZeroes)

Creates image with pixels optionally set to zero.

Accumulator32

public Accumulator32(java.awt.image.BufferedImage bim)
              throws IncompatibleImageException

Use the BufferedImage to set the width, height and number of bands (channels) in this Image. Populate the pixel values in the image data array from the BufferedImage also.

Throws:

IncompatibleImageException

Accumulator32

public Accumulator32(Image im)
              throws IncompatibleImageException

Use the Image to set the width, height and number of bands (channels) in this Accumulator. Populate the pixel values in the Accumulator data array from the Image also.

Throws:

IncompatibleImageException

Method Detail

addWithStarBoost

public void addWithStarBoost(Image image,
                             int starBoostFactor)
                      throws IncompatibleImageException

For accumulating star trails. The starBoostFactor should be something like the number of images being accumulated.

Specified by:

addWithStarBoost in interface Accumulator

Throws:

IncompatibleImageException

brightestShiftAccumulate

public boolean brightestShiftAccumulate(Image image,
                                        int imNo,
                                        int middleImNo,
                                        java.util.List<PointFloat> centres)
                                 throws IncompatibleImageException

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. The reason for this is that when matching on single bright objects we may mean the moon, nearly filling the image, in which case we would run out of memory if holding all details of that for every image in a sequence.

Specified by:

brightestShiftAccumulate in interface Accumulator

Throws:

IncompatibleImageException

averageShiftAccumulate

public boolean averageShiftAccumulate(Image image,
                                      int imNo,
                                      int middleImNo,
                                      java.util.List<MatchPair> matches,
                                      BlobMeas[][] lookup,
                                      int nBrightest)
                               throws IncompatibleImageException

For image imNo of a sequence, add the pixel values into the accumulator but first shift the image so that matched point pairs are superimposed. Use the average translation vector from all matched objects.
NB: Does NOT set this.extremes, so must call getOverallRange () at end of sequence.

Specified by:

averageShiftAccumulate in interface Accumulator

Throws:

IncompatibleImageException

warpAccumulate

public boolean warpAccumulate(Image image,
                              int imNo,
                              int middleImNo,
                              java.util.List<MatchPair> matches,
                              BlobMeas[][] lookup,
                              int nBrightest)
                       throws IncompatibleImageException

For image imNo of a sequence, add the pixel values into the accumulator but first distort the image so that matched point pairs are superimposed. Return false if not able to warp the image.
NB: Does NOT set this.extremes, so must call getOverallRange () at end of sequence.

Specified by:

warpAccumulate in interface Accumulator

Throws:

IncompatibleImageException
