Member Function Documentation

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:
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 in firevision::FilterClosing, and firevision::FilterOpening.

Definition at line 67 of file morphologicalfilter.cpp.
