typedef ValueType | second_argument_type
typedef SquareRootTraits< typename NormTraits< ValueType >::SquaredNormType >::SquareRootResult | result_type

## Public Methods

## Detailed Description

### template<class ValueType>
class vigra::MagnitudeFunctor< ValueType >

Calculate the magnitude from two arguments. Can be used in conjunction with gradientBasedTransform().

If the gradient is represented by a vector-valued image instead of a pair of scalar images, use vigra::VectorNormFunctor.

Traits defined:

`FunctorTraits::isBinaryFunctor` are true (`VigraTrueType`)``

## Member Typedef Documentation

typedef ValueType first_argument_type

| the functor's first argument type

typedef SquareRootTraits<typename NormTraits<ValueType>::SquaredNormType>::SquareRootResult result_type

| the functor's result type

typedef ValueType second_argument_type

| the functor's second argument type

typedef ValueType value_type

| Deprecated: use first_argument_type, second_argument_type, result_type

## Member Function Documentation

result_type operator() | ( | first_argument_type const & | v1,
|  | second_argument_type const & | v2
| ) | const`[inline]`

| calculate transform '`sqrt(squaredNorm(v1) + squaredNorm(v2))`'.
