typedef struct mirkl_image_t_ mirkl_image_t

Image structure.

Function Documentation

mirkl_img_circle()

mirkl_error_t * mirkl_img_circle	(	int	x0,
		int	y0,
		int	r,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Process pixels of a circle using fast Bresenham's Midpoint circle algorithm. see http://members.chello.at/~easyfilter/bresenham.html.

Parameters

x0,y0	Coordinates (in pixels) of the center of the circle.
r	Circle radius (in pixels).
pproc	User-defined callback function, arguments of this function are coordinates of the currently processed pixel, its weight and pointer to user data. In this function weights are always 1.0.
args	User-defined data.

mirkl_img_circle_aa()

mirkl_error_t * mirkl_img_circle_aa	(	int	xm,
		int	ym,
		int	r,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Similar to mirkl_img_circle function, but processes pixels with anti-aliasing method sending appropriate weights to callback function. see http://members.chello.at/~easyfilter/bresenham.html

mirkl_img_circle_waa()

mirkl_error_t * mirkl_img_circle_waa	(	int	xm,
		int	ym,
		int	r,
		double	th,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Similar to mirkl_img_circle_aa function, plus a possibility to defined circle thickness.

Parameters

th	Circle thickness in pixels.

mirkl_img_ellipse()

mirkl_error_t * mirkl_img_ellipse	(	int	xm,
		int	ym,
		int	a,
		int	b,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Process pixels of an ellipse. The ellipse is defined by coordinates of the center and by axes lengths.

Parameters

xm,ym	Coordinates (in pixels) of the center.
a,b	Axes lengths (in pixels), a is along x-axis (width), b is along y-axis (length).
pproc	User-defined callback function, arguments of this function are coordinates of the currently processed pixel, its weight and pointer to user data. In this function weights are always 1.0.
args	User-defined data.

mirkl_img_ellipse_aa()

mirkl_error_t * mirkl_img_ellipse_aa	(	int	xm,
		int	ym,
		int	a,
		int	b,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Same as mirkl_img_ellipser_aa, but the ellipse is defined by coordinates of the center and axes length.

mirkl_img_ellipse_waa()

mirkl_error_t * mirkl_img_ellipse_waa	(	int	xm,
		int	ym,
		int	a,
		int	b,
		double	th,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Same as mirkl_img_ellipser_waa, but the ellipse is defined by coordinates of the center and axes length.

mirkl_img_ellipser()

mirkl_error_t * mirkl_img_ellipser	(	int	x0,
		int	y0,
		int	x1,
		int	y1,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Process pixels of an ellipse. The ellipse is defined by a rectangle.

Parameters

x0,y0	Coordinates (in pixels) of the upper-left vertex of the rectangle.
x1,y1	Coordinates (in pixels) of the lower-right vertex of the rectangle.
pproc	User-defined callback function, arguments of this function are coordinates of the currently processed pixel, its weight and pointer to user data. In this function weights are always 1.0.
args	User-defined data.

mirkl_img_ellipser_waa()

mirkl_error_t * mirkl_img_ellipser_waa	(	int	x0,
		int	y0,
		int	x1,
		int	y1,
		double	th,
		mirkl_error_t *(*)(int, int, double, void *)	pproc,
		void *	args
	)

Process pixels of an ellipse using fast Bresenham's algorithm. Anti-aliasing is used and ellipse thickness can be defined. see http://members.chello.at/~easyfilter/bresenham.html The ellipse is defined by a rectangle.

Parameters

x0,y0	Coordinates (in pixels) of the upper-left vertex of the rectangle.
x1,y1	Coordinates (in pixels) of the lower-right vertex of the rectangle.
th	Ellipse thickness (in pixels, fractions of pixels).
pproc	User-defined callback function, arguments of this function are coordinates of the currently processed pixel, its weight and pointer to user data. In this function weights are always 1.0.
args	User-defined data.

mirkl_img_thres_IJ()

double mirkl_img_thres_IJ	(	mirkl_uint64_t	nbins,
		mirkl_uint64_t *	data
	)

Image thresholding. Default method of ImageJ.

Parameters

data	Histogram of image.
nbins	Number of intensity levels in image (number of elements in array data).
