  • Method Details

    • threshold

      boolean threshold(ByteProcessor ip)
      Thresholds the specified ByteProcessor (8-bit image), which is modified. Does nothing and returns true if no valid threshold could be found (e.g., if all image pixels have the same value).
      Parameters:
      ip - a ByteProcessor (8-bit image)
      Returns:
      true iff the operation was successful
