(

BufferedImage

in

)

[static]

Get an image histogram.

Image must be in gray-mode.

Parameters:

in

image

Returns:

the histogram

static Histogram org.miv.jism.tools.JismTools.getHistogram	(	BufferedImage	in,
		boolean	log
	)			[static]

Get an image histogram.

Image must be in gray-mode.

Parameters:

	in	image
	log	true if histogram must show logarithmic values

Returns:

the histogram

static Histogram org.miv.jism.tools.JismTools.getLocalHistogram	(	JismContext	in,
		boolean	log
	)			[static]

Get an histogram of an image part.

Image must be in gray-mode.

Parameters:

	in	image
	log	true if histogram must show logarithmic values

Returns:

the histogram

static Histogram org.miv.jism.tools.JismTools.getLocalHistogram	(	JismContext	in,
		int	xstart,
		int	ystart,
		int	xend,
		int	yend,
		boolean	log
	)			[static]

Get an histogram of an image part.

Image must be in gray-mode.

Parameters:

	in	image
	xstart	start x of the part
	ystart	start y of the part
	xend	end x of the part
	yend	end y of the part
	log	true if histogram must show logarithmic values

Returns:

the histogram

static Histogram org.miv.jism.tools.JismTools.getLocalHistogram	(	JismContext	in,
		int	xstart,
		int	ystart,
		int	xend,
		int	yend,
		int	zstart,
		int	zend,
		boolean	log
	)			[static]

Get an histogram of an image part.

Image must be in gray-mode.

Parameters:

	in	image
	xstart	start x of the part
	ystart	start y of the part
	xend	end x of the part
	yend	end y of the part
	log	true if histogram must show logarithmic values

Returns:

the histogram

static LinkedList<Integer> org.miv.jism.tools.JismTools.searchOptimum

(

Histogram

grays

)

[static]

Search the optimums of the histogram.

Parameters:

grays

the histogram

Returns:

linked list of optimum values

static LinkedList<Integer> org.miv.jism.tools.JismTools.searchOptimum	(	Histogram	grays,
		int	desire
	)			[static]

Search the optimums of the histogram.

Desired number of optimums can be specified but with no warranty that it will be this !

Parameters:

	grays	the histogram
	desire	desired optimums count

Returns:

linked list of optimum values
