Interface CoOccurrenceMatrix

  • All Known Implementing Classes:
    MemoryCoOccurrenceMatrix
    public interface CoOccurrenceMatrix
    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 Detail

      • clear

        void clear()
        Sets all counters to zero.

      • getDimension

        int getDimension()
        Returns the dimension of this matrix. This is the number of rows and columns.
        Returns:
        matrix dimension (larger than zero)

      • incValue

        void incValue​(int i,
              int j)
        Increases the counter for pair (i, j) by one. This method can be implemented by the call setValue(i, j, getValue(i, j) + 1);.
        Parameters:
        i - column index, from 0 to getDimension() - 1
        j - row index, from 0 to getDimension() - 1
        Throws:
        IllegalArgumentException - for invalid index pairs (i, j)

      • setValue

        void setValue​(int i,
              int j,
              int newValue)
        Sets the counter for pair (i, j) to a new value.
        Parameters:
        i - column index, from 0 to getDimension() - 1
        j - row index, from 0 to getDimension() - 1
        Throws:
        IllegalArgumentException - for invalid index pairs (i, j)
