SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
An interface for co-occurrence matrices.
An implementing class stores int
counter values for pairs of pixels.
These counters represent the number of times two pixels are direct
neighbors in an image.
Method Summary | |
void |
clear()
Sets all counters to zero. |
int |
getDimension()
Returns the dimension of this matrix. |
int |
getValue(int i,
int j)
Returns the matrix value at a given position. |
void |
incValue(int i,
int j)
Increases the counter for pair (i, j) by one. |
void |
setValue(int i,
int j,
int newValue)
Sets the counter for pair (i, j) to a new value. |
