| LDA | ( | InputArrayOfArrays | src, |
| InputArray | labels, | ||
| int | num_components = 0 |
||
| ) |
Initializes and performs a Discriminant Analysis with Fisher's Optimization Criterion on given data in src and corresponding labels in labels.
If 0 (or less) number of components are given, they are automatically determined for given data in computation.
