Detailed Description

template<typename _Tp>
class cv::Scalar_< _Tp >

Template class for a 4-element vector derived from Vec.

Being derived from Vec<_Tp, 4> , Scalar_ and Scalar can be used just as typical 4-element vectors. In addition, they can be converted to/from CvScalar . The type Scalar is widely used in OpenCV to pass pixel values.
