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:
bufBuffer to use as destination image
roiRegion 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:
bufBuffer to use as source image
roiRegion Of Interest to work on
oriOrientation to apply the filter in, maybe ignored in some filters
buffer_numsource buffer to set for filter that need multiple src buffers
Exceptions:
OutOfBoundsExceptionThrown 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:
bufBuffer to use as source image
roiRegion Of Interest to work on
buffer_numsource buffer to set for filter that need multiple src buffers
Exceptions:
OutOfBoundsExceptionThrown 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:
sestructuring 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_widthwidth of structuring element
se_heightheight of structuring element
se_anchor_xx coordinate of anchor in structuring element
se_anchor_yy coordinate of anchor in structuring element

Reimplemented from firevision::MorphologicalFilter.
