  • Field Details

    • zChange

      protected int zChange
      The change in the Z-dimension to reach this neighbor relative to the source coordinate.

    • sourceValue

      protected int sourceValue
      The intensity value of the source voxel.

    • initSource

      public void initSource​(int sourceValue, int sourceOffsetXY)
      Description copied from interface: ProcessVoxelNeighborAbsolute
      The value and offset for the source point (around which we process neighbors).

      This function should always be called before ProcessVoxelNeighborAbsolute.processPoint(int, int, int, int).

      It can be called repeatedly for different points (resetting state each time).

      Specified by:
      initSource in interface ProcessVoxelNeighborAbsolute<T>
      Parameters:
      sourceValue - the intensity value of the source voxel.
      sourceOffsetXY - the offset of the source voxel in XY.

    • notifyChangeZ

      public void notifyChangeZ​(int zChange, int z)
      Description copied from interface: ProcessVoxelNeighborAbsolute
      Notifies the processor that there has been a change in z-coordinate.
      Specified by:
      notifyChangeZ in interface ProcessVoxelNeighborAbsolute<T>
      Parameters:
      zChange - the change in the Z-dimension to reach this neighbor relative to the source coordinate.
      z - the Z-dimension coordinates for this point (the neighboring point) in global (absolute) terms i.e. not relative to a bounding-box.

    • extent

      public Extent extent()
      The size of the associated SlidingBuffer.
      Returns:
      the size.

    • changedOffset

      protected int changedOffset​(int xChange, int yChange)
      Calculates the offset in the buffer for a voxel, indicated by its relative-change in position.
      Parameters:
      xChange - the relative change in the X-dimension, compared to the current buffer position.
      yChange - the relative change in the Y-dimension, compared to the current buffer position.
      Returns:
      the position in the buffer where the value is located.

    • getInt

      protected int getInt​(int index)
      Get a value from the buffer at a particular absolute position.
      Parameters:
      index - the absolute position in the buffer.
      Returns:
      the value as an unsigned int.

    • getInt

      protected int getInt​(int xChange, int yChange)
      Get a value from the buffer at a particular relative position.
      Parameters:
      xChange - the relative change in the X-dimension, compared to the current buffer position.
      yChange - the relative change in the Y-dimension, compared to the current buffer position.
      Returns:
      the value as an unsigned int.

    • putInt

      protected void putInt​(int index, int valueToAssign)
      Assign a value to the buffer at a particular absolute position.
      Parameters:
      index - the absolute position in the buffer.
      valueToAssign - the value to assign.
