Performance comparison of the proposed method for partially occluded facial image retrieval in the case of occlusion by a scarf.
| Algorithm | Image format used in SIFT matching | Number of subregions | Retrieval rate |
| Gabor-LBP [26] | Without SQI | 6 × 6 | 91.85% | 10 × 10 | 97.04% | With SQI | 6 × 6 | 91.85% | 10 × 10 | 97.94% |
| SIFT total weight [35] | Without SQI | 6 × 6 | 94.07% | 10 × 10 | 94.07% | With SQI | 6 × 6 | 92.60% | 10 × 10 | 95.56% |
| SIFT probe weight [36] | Without SQI | 6 × 6 | 94.07% | 10 × 10 | 94.07% | With SQI | 6 × 6 | 93.33% | 10 × 10 | 88.89% |
| Proposed method | Without SQI | 6 × 6 | 87.41% | 10 × 10 | 91.11% | With SQI | 6 × 6 | 93.33% | 10 × 10 | 91.11% |
