Member Function Documentation

void firevision::SEGenerator::drawSE	(	unsigned char *	yuv422planar_buffer,
		unsigned char *	mask,
		unsigned int	width,
		unsigned int	height
	)		[static]

Draw structuring element.

This draws the structuring element to an image buffer.

Parameters:

yuv422planar_buffer	image buffer
mask	structuring element
width	width of structuring element
height	height of structuring element

Definition at line 169 of file segenerator.cpp.

void firevision::SEGenerator::drawSEbw	(	unsigned char *	yuv422planar_buffer,
		unsigned char *	mask,
		unsigned int	width,
		unsigned int	height
	)		[static]

Draw structuring element.

This draws the structuring element to a b/w image buffer.

Parameters:

yuv422planar_buffer	image buffer
mask	structuring element
width	width of structuring element
height	height of structuring element

Definition at line 190 of file segenerator.cpp.

unsigned char * firevision::SEGenerator::linear	(	unsigned int	width,
		unsigned int	height,
		unsigned int *	proposed_center_x,
		unsigned int *	proposed_center_y,
		float	slope_angle_rad
	)		[static]

Generate linear structuring element.

Parameters:

width	width of structuring element
height	height of structuring element
proposed_center_x	contains the proposed x coordinate of the anchor upon return
proposed_center_y	contains the proposed y coordinate of the anchor upon return
slope_angle_rad	the slope of the line in radians

Returns:

buffer with linear structuring element. The buffer has been allocated using malloc(). Use free() to free the memory after you are done with it.

Definition at line 60 of file segenerator.cpp.

unsigned char * firevision::SEGenerator::square	(	unsigned int	width,
		unsigned int	height
	)		[static]

Generate square structuring element.

Parameters:

width	width of structuring element
height	height of structuring element

Returns:

buffer with square structuring element. The buffer has been allocated using malloc(). Use free() to free the memory after you are done with it.

Definition at line 153 of file segenerator.cpp.
