Parameters to be tuned in each description method.
| Descriptor | Parameters |
| FS | components per row, localization descriptor | componentes per row, orientation descriptor |
| r-PCA | number of eigenvectors | number of rotations per panoramic image |
| HOG | number of bins per histogram | number of horizontal cells, localization descriptor | width of vertical cells, orientation descriptor | distance between vertical cells, orientation descriptor | number vertical cells, orientation descriptor |
| Gist | number of orientations (Gabor filters), localization descriptor | number of horizontal blocks, localization descriptor | width of vertical blocks, orientation descriptor | distance between vertical blocks, orientation descriptor | number of vertical blocks, orientation descriptor |
