/** \class NotImageFilter
 * \brief Implements the NOT logical operator pixel-wise on an image.
 *
 * This class is templated over the type of an
 * input image and the type of the output image.
 * Numeric conversions (castings) are done by the C++ defaults.
 *
 * Since the logical NOT operation operates only on boolean types,
 * the input type must be implicitly convertible to bool, which 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
 *

       {
       return this->m_ForegroundValue;
       }
     return this->m_BackgroundValue;
   \endcode
 *
 * Where "!" is the unary Logical NOT operator in C++.
