Member Enumeration Documentation

Type of connexity 4, or 8.

Enumerator
CONNEXITY_4 

For a given pixel 4 neighbors are considered (left, right, up, down)

CONNEXITY_8 

For a given pixel 8 neighbors are considered (left, right, up, down, and the 4 pixels located on the diagonal)

void vpImageMorphology::dilatation ( vpImage< Type > &  I,
Type  value,
Type  value_out,
vpConnexityType  connexity = CONNEXITY_4 
)
static

Dilate a binary image using a structuring element of size one.

Parameters
I: Image to process.
value: Values of the pixels to dilate.
value_out: Value to set if dilatation is done.
connexity: Type of connexity: 4 or 8.

To dilate a black area in an unsigned char image with one element mask, set value to 0 and value_out to 255.

To dilate a white area in an unsigned char image with one element mask, set value to 255 and value_out to 0.

void vpImageMorphology::erosion ( vpImage< Type > &  I,
Type  value,
Type  value_out,
vpConnexityType  connexity = CONNEXITY_4 
)
static

Erode a binary image using a structuring element of size one.

Parameters
I: Image to process.
value: Values of the pixels to erode.
value_out: Value to set if erosion is done.
connexity: Type of connexity: 4 or 8.

To erode a black area in an unsigned char image, set value to 0 and value_out to 255.

To erode a white area in an unsigned char image with one element mask, set value to 255 and value_out to 0.
