◆ Euclidian() [1/2]
template<typename Targ = float, typename Tres = float>
| Tres DirectGraphicalModels::mathop::Euclidian |
( |
const Mat & |
a, |
|
|
const Mat & |
b |
|
) |

Calculates the Euclidian distance between argument matrices a and b.
The Euclidian distance is calculated by the formula : \(D_E(a, b) = \sqrt{ \sum_{i,j}(a_{ij} - b_{ij})^2 }\).
This function is about 10 times faster then cv::norm(a, b, NORM_L2);
- Template Parameters
-
| Targ | Type of elements in matrices a and b (e.g. byte, float, double, etc.) |
| Tres | Type of the resulting distance (float or double) |
- Parameters
-
| a | The first matrix |
| b | The second matrix |
- Returns
- The Euclidian distance : \(D_E(a, b)\)

| bool DirectGraphicalModels::mathop::ifOverlap |
( |
pair_mat_t & |
box1, |
|
|
pair_mat_t & |

| T | The type of the elemets, defining the regions box1 and box2 |
- Return values
-
| true | if regions overlap |
| false | otherwise |
