Constructor & Destructor Documentation

firevision::MorphologicalFilter::MorphologicalFilter	(	const char *	name,
		unsigned int	max_num_buffers = `1`
	)

Constructor.

Parameters:

name	filter name
max_num_buffers	maximum number of source buffers.

Definition at line 43 of file morphologicalfilter.cpp.

firevision::MorphologicalFilter::~MorphologicalFilter ( )

virtual

Destructor.

Definition at line 52 of file morphologicalfilter.cpp.

void firevision::MorphologicalFilter::set_structuring_element	(	unsigned char *	se,
		unsigned int	se_width,
		unsigned int	se_height,
		unsigned int	se_anchor_x,
		unsigned int	se_anchor_y
	)

virtual

Set the structuring element for successive filter runs.

Parameters:

se	structuring element buffer. This is just a line-wise concatenated array of values. A value of zero means ignore, any other value means to consider this value.
se_width	width of structuring element
se_height	height of structuring element
se_anchor_x	x coordinate of anchor in structuring element
se_anchor_y	y coordinate of anchor in structuring element
