Fisher vector options | |
| #define | VL_FISHER_FLAG_SQUARE_ROOT (0x1 << 0) |
| Use signed squared-root (Normalization and improved Fisher vectors). | |
| #define | VL_FISHER_FLAG_NORMALIZED (0x1 << 1) |
| Gobally normalize the Fisher vector in L2 norm (Normalization and improved Fisher vectors). | |
| #define | VL_FISHER_FLAG_IMPROVED (VL_FISHER_FLAG_NORMALIZED|VL_FISHER_FLAG_SQUARE_ROOT) |
Improved Fisher vector. This is the same as VL_FISHER_FLAG_SQUARE_ROOT|VL_FISHER_FLAG_NORMALIZED. | |
| #define | VL_FISHER_FLAG_FAST (0x1 << 2) |
| Fast but more approximate calculations (Faster computations). Keep only the larges data to cluster assignment (posterior). | |
