MorphologicalKernel2d
Represents a 3x3 kernel dedicated to be applied on a binary image. Each kernel element can be assigned to one of three different values.
A 2D morphological kernel contains exactly 9 values and indexes matching the following table:
[432501678]
Accepted values for the kernel are:
- ZERO: pixel is off
- ONE: pixel is on
- ANY: pixel is ignored
Syntax
Method |
Description |
Ptr New( Value value = ZERO ) |
Constructor returning a kernel with all elements initialized with the same value
value: the value to assign.
|
Value getValue( int index ) |
get the value of a specific kernel's element at the position index
index: the position of the kernel's element between 0 and 8.
|
void setValue( int index, Values value ) |
Assigns a value to a specific kernel's element
index: the position of the kernel's element between 0 and 8.
value: the value to assign.
|
void setAllValues(Values value = ZERO ) |
Assigns the same value to all kernel elements.
value: the default value for all of a kernel's elements.
|
void rotate( size_t rotation = 1 ) |
Applies a direct rotation of a PI/4 multiple to the kernel.
[432501678] =>[321408567]
rotation: the number of rotations of PI/4.
