vec3b

/*!
  A short numerical vector.


  This template class represents short numerical vectors (of 1, 2, 3, 4 ... elements)
  on which you can perform basic arithmetical operations, access individual elements using [] operator etc.
  The vectors are allocated on stack, as opposite to std::valarray, std::vector, cv::Mat etc.,
  which elements are dynamically allocated in the heap.


  The template takes 2 parameters:
  -# _Tp element type
  -# cn the number of elements


  In addition to the universal notation like Vec<float, 3>, you can use shorter aliases
  for the most popular specialized variants of Vec, e.g. Vec3f ~ Vec<float, 3>.
