Member Function Documentation

void firevision::FilterOpening::apply ( )

virtual

Apply the filter.

Apply the filter to the given source and destination buffers with given width and height and orientation (ori may be ignored for some filters).

Implements firevision::Filter.

Definition at line 98 of file opening.cpp.

References firevision::FilterErosion::apply(), and firevision::FilterDilation::apply().

void firevision::FilterOpening::set_dst_buffer	(	unsigned char *	buf,
		ROI *	roi
	)

virtual

Set the destination buffer.

Parameters:

buf	Buffer to use as destination image
roi	Region Of Interest where the result is put in the dst image

Reimplemented from firevision::Filter.

Definition at line 78 of file opening.cpp.

References firevision::Filter::set_dst_buffer(), and firevision::Filter::set_src_buffer().

void firevision::FilterOpening::set_src_buffer	(	unsigned char *	buf,
		ROI *	roi,
		orientation_t	ori = `ORI_HORIZONTAL`,
		unsigned int	buffer_num = `0`
	)

virtual

Set source buffer with orientation.

Parameters:

buf	Buffer to use as source image
roi	Region Of Interest to work on
ori	Orientation to apply the filter in, maybe ignored in some filters
buffer_num	source buffer to set for filter that need multiple src buffers

Exceptions:

OutOfBoundsException Thrown if buffer_num is illegal

Reimplemented from firevision::Filter.

void firevision::FilterOpening::set_src_buffer	(	unsigned char *	buf,
		ROI *	roi,
		unsigned int	buffer_num
	)

virtual

Set source buffer.

Parameters:

buf	Buffer to use as source image
roi	Region Of Interest to work on
buffer_num	source buffer to set for filter that need multiple src buffers

Exceptions:

OutOfBoundsException Thrown if buffer_num is illegal

Reimplemented from firevision::Filter.

void firevision::FilterOpening::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

Reimplemented from firevision::MorphologicalFilter.

Definition at line 87 of file opening.cpp.
