This method returns which pixel range around the interpolated postition is considered by the interpolation functor.
This is very useful for other functors to decide whether they should call the interpolate() methods or the faster interpolateUnchk() methods.
If the returned value is 
and the interpolated position is 
all pixels with coordinates in ![$ [x-a .. x+a] \times [y-a .. y+a] $](form_0.png)
may be considered by the interpolation functor.

| T cvr::nearestNeighborInterpolation< T >::interpolate | ( | const matrix< T > & | src, | |
| const float | row, | |||
| const float | col | |||
| ) | const [inline] |
Returns the interpolated value of the matrix at the real valued position (row,col).
This method is not virtual and can be used if this interpolation type is used as template parameter in time critical situations
| src | matrix<T> with the source data. | |
| row | which row | |

| T cvr::nearestNeighborInterpolation< T >::interpolateUnchk | ( | const matrix< T > & | src, | |
| const float | row, | |||
| const float | col | |||
| ) | const [inline] |
Returns the interpolated value of the matrix at the real valued position (row,col).
This method does not check if the given coordinates and the rest of used points in the src matrix lie within the valid range. This is left to you.
This method is not virtual and can be used in time critical situations, where you prefer to take the boundary control by yourself.
| src | matrix<T> with the source data. | |

| virtual const std::string& cvr::nearestNeighborInterpolation< T >::name | ( | ) | const [virtual] |
returns the name of this type ("nearestNeighborInterpolation")
