Member Function Documentation

void 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 164 of file segenerator.cpp.

void 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 185 of file segenerator.cpp.

unsigned char * 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.

unsigned char * 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.
