Enumeration Type Documentation

enum iwRegMode

Enumerator:

IW_REG_INCLUSION	Calculate inclusion
IW_REG_NO_ZERO	Ignore regions with a label of 0

enum iwRegThinning

Enumerator:

IW_REG_THIN_OFF	Don't perform any thinning
IW_REG_THIN_ABS	Only leave every nth point
IW_REG_THIN_DIST	Only leave points which are farther away than the threshold

Function Documentation

int iw_reg_label	(	int	xsize,
		int	ysize,
		const uchar *	color,
		gint32 *	region
	)

Do a region labeling of the image color (size: xsize x ysize) and
write the result to region.
Return: Number of regions.

iwRegCOMinfo* iw_reg_label_with_calc	(	int	xsize,
		int	ysize,
		const uchar *	color,
		gint32 *	region,
		int *	nregions,
		int	minPixelCount
	)

Do a region labeling of the image color (size: xsize x ysize) and
write the result to region. Calculate pixel count, color, and COM
of the regions.
pixel count < minPixelCount -> Pixel count of the region = 0
Return value is a pointer to a static variable!

iwRegCalcData* iw_reg_data_create ( void )

Maintain the struct holding settings for the region calculation.
The different settings are:
color : Classified image (supported: 1 plane, IW_8U, IW_16U, and
IW_32S), used to get a color index
orig_img: Original color image, used to get the average region color
confimg : Confidence mapped image from the color classifier.
!= NULL: regionen->avgConf = average confidence value of
the region
minPixelCount: Minimal size of calculated regions
iwRegMode|iwRegThinning: See the flags above.
maxdist : Distance value for the modes IW_REG_THIN_ABS and
IW_REG_THIN_DIST.

void iw_reg_data_free ( iwRegCalcData * data )

void iw_reg_data_set_images	(	iwRegCalcData *	data,
		iwImage *	color,
		uchar **	orig_img,
		uchar *	confimg
	)

void iw_reg_data_set_minregion	(	iwRegCalcData *	data,
		int	minPixelCount
	)

void iw_reg_data_set_mode	(	iwRegCalcData *	data,
		iwRegMode	mode
	)

void iw_reg_data_set_thinning	(	iwRegCalcData *	data,
		iwRegThinning	mode,
		float	maxdist
	)

iwRegion* iw_reg_calc_data	(	int	xlen,
		int	ylen,
		gint32 *	image,
		int *	num_reg,
		iwRegCalcData *	data
	)

Calculate regions from the image "image".
xlen, ylen: Size of image
image : Region labeld image
num_reg : in : Number of labeld regions
out : Number of calculated regions
data : Additional settings for the region calculation.

iwRegion* iw_reg_calc	(	int	xlen,
		int	ylen,
		uchar *	color,
		gint32 *	image,
		uchar **	orig_img,
		uchar *	confimg,
		int *	num_reg,
		int	doEinschluss,
		int	minPixelCount
	)

iwRegion* iw_reg_calc_img	(	int	xlen,
		int	ylen,
		iwImage *	color,
		gint32 *	image,
		uchar **	orig_img,
		uchar *	confimg,
		int *	num_reg,
		iwRegMode	mode,
		int	minPixelCount
	)

void iw_reg_stretch	(	int	width,
		int	height,
		iwRegion *	reg,
		int	scale
	)

Stretch region reg by scale pixels in all directions and
restrict the region to a size of width x height.

void iw_reg_boundingbox	(	const Polygon_t *	p,
		int *	x1,
		int *	y1,
		int *	x2,
		int *	y2
	)

Return bounding box of polygon p.

void iw_reg_upsample	(	int	nregions,
		iwRegion *	regions,
		float	upw,
		float	uph
	)

Upsample regions by factor (upw,uph).

void iw_reg_free	(	int	nregions,
		iwRegion *	regions
	)

Free regions allocated with iw_reg_copy(). Attention: This works
only correctly for regions allocated with iw_reg_copy().

iwRegion* iw_reg_copy	(	int	nregions,
		const iwRegion *	regions
	)

Return a copy of regions. Attention: Single regions can't be freed
as all points and polygons are malloced en bloc.
