  /** \class OrImageFilter
   * \brief Implements the OR bitwise operator pixel-wise between two images.
   *
   * This class is templated over the types of the two
   * input images and the type of the output image.
   * Numeric conversions (castings) are done by the C++ defaults.
   *
   * Since the bitwise OR operation is only defined in C++ for integer
   * types, the images passed to this filter must comply with the requirement
   * of using integer pixel type.
   *
   * The total operation over one pixel will be
   *
     \code
      output_pixel = static_cast<OutputPixelType>( input1_pixel | input2_pixel )
     \endcode
   *
   * Where "|" is the boolean OR operator in C++.
