autoThreshold

public ByteMask autoThreshold()

Threshold automatically. First gets a histogram and finds the channel means. Sets the threshold for each channel: if the mean is lower than half-way up the brightness range the background is assumed to be dark so the threshold goes from half-way up to the top. Otherwise the background is assumed to be bright so the threshold goes from 0 to half-way. Then does the thresholding to set a mask in the GlassPane, suitable for blob detection.
Not for segmenting stars: use StarSegmenter class instead.

Specified by:: neutraliseBackground in interface Image

rankFilter

public void rankFilter(int halfWidth,
                       javax.swing.ProgressMonitor monitor)

Replace every pixel in the image by its rank in its n x n neighbourhood, where n = 2.halfWidth + 1. The rank is scaled up so that its possible values span the grey level range of the image. Each channel is treated independently.

Specified by:: rankFilter in interface Image

reapplyColour

public void reapplyColour(Image intensityImage,
                          Image colourImage)

Description copied from interface: Image

For combining a monochrome intensity image with a multi-band colour information image, the 2 images having been created by ImProcess.splitIntensity (). The result fills the current Image, overwriting any previous contents.

Specified by:: reapplyColour in interface Image

rotate

public void rotate(double angleDegs)

Rotate the image anticlockwise by the given angle (in degrees).

Specified by:: rotate in interface Image

save

public void save(java.lang.String filePath)

Save image as a file. FITS or any format supported by JAI may be used. The format is indicated by the extension at the end of the path. Metadata will be written in the standard format (javax_imageio_1.0) if the writer supports it.

Specified by:: save in interface Image

save

public void save(java.lang.String filePath,
                 RangeInt range)

Save image as a file. In the case of 8 and 16 bit images this simply calls save(), so the second parameter is ignored and may be null.

save

public void save(java.lang.String filePath,
                 RangeDouble range)

Save image as a file. In the case of 8 and 16 bit images this simply calls save(), so the second parameter is ignored and may be null.

Specified by:: save in interface Image

saveAsFITS

public void saveAsFITS(java.lang.String filePath)

This is called by save() if the filePath ends in ".fits" but it may be called directly.

Specified by:: saveAsFITS in interface Image

public void scale(double factor,
                  boolean interpolating)

Scale the image by the given factor

Specified by:: scale in interface Image

set

public void set(java.awt.image.BufferedImage bim)
         throws IncompatibleImageException

Description copied from interface: Image

Set pixel values from bim into the data array. If bim is larger than the data then the rectangle starting at the top left corner of bim which overlaps the data will be used.

Specified by:: set in interface Image

Throws:: IncompatibleImageException

setMetadata

public void setMetadata(Metadata theData)

Description copied from class: ImageBase

Associate metadata with the image.

Specified by:: setMetadata in interface Image
Overrides:: setMetadata in class ImageBase

setPixel

public void setPixel(int x,
                     int y,
                     int[] px)

Description copied from interface: Image

Does nothing if (x, y) is outside the image.

Specified by:: setPixel in interface Image

setPixel

public void setPixel(int x,
                     int y,
                     int band,
                     int px)

Description copied from interface: Image

Set value into a single band of a pixel without changing the other bands. Does nothing if (x, y) is outside the image.

Specified by:: setPixel in interface Image

setPixelDouble

public void setPixelDouble(int x,
                           int y,
                           double[] px)

Description copied from interface: Image

Does nothing if (x, y) is outside the image.

Specified by:: setPixelDouble in interface Image

setPixelDouble

public void setPixelDouble(int x,
                           int y,
                           int band,
                           double px)

Description copied from interface: Image

Set value into a single band of a pixel without changing the other bands. Does nothing if (x, y) is outside the image.

Specified by:: setPixelDouble in interface Image

showInfo

public void showInfo()

Display information about the current image in a dialogue.

Specified by:: showInfo in interface Image

subtract

public void subtract(Image other)
              throws IncompatibleImageException

Subtract pixel values of other image from this image data array, raising result by minimum possible so it is always positive. If other is larger than this image then the rectangle starting at the top left corner of other which overlaps this image will be used.

Specified by:: subtract in interface Image

Throws:: IncompatibleImageException

subtractToZero

public void subtractToZero(Image other)
                    throws IncompatibleImageException

Subtract pixel values of other image from this image data array, clipping negative results to zero. If other is larger than this image then the rectangle starting at the top left corner of other which overlaps this image will be used.

Specified by:: subtractToZero in interface Image

Throws:: IncompatibleImageException

threshold

public ByteMask threshold(Threshold thresh)

Threshold the image to detect pixels in the range(s) specified by the given threshold. Return a binary mask (values BlobMask.MASK_CLEAR or BlobMask.MASK_SET), suitable for setting into GlassPane. The image may have any number of bands.

Specified by:: threshold in interface Image

translate

public void translate(int dx,
                      int dy)

Displace the image content by the given offset vector, a whole number of pixels. Image size is unchanged. Margins exposed by the shift are filled with zeroes. Portions of the image shifted off the edge are lost. Shifting an image by a very small amount and then subtracting it from itself (eg, as previously cloned) is a way of detecting edges in the direction of the offset.

Specified by:: translate in interface Image

translate

public void translate(double dx,
                      double dy)

Displace the image content by the given offset vector, interpolating between pixels. Image size is unchanged. Margins exposed by the shift are filled with zeroes. Portions of the image shifted off the edge are lost. Shifting an image by a very small amount and then subtracting it from itself (eg, as previously cloned) is a way of detecting edges in the direction of the offset.

Specified by:: translate in interface Image

varianceFilter

public void varianceFilter(int halfWidth,
                           javax.swing.ProgressMonitor monitor)

Replace every pixel in the image by the variance of its n x n neighbourhood, where n = 2.halfWidth + 1.

Specified by:: varianceFilter in interface Image

toFoldedString

public java.lang.String toFoldedString(java.lang.String lineEnd)

Description copied from interface: Image

Return complete metadata in a form suitable for display. The lineEnd might be "\n" or "
", depending on the intended output medium.
