HOG and symmetric log-chamfer image matching identify individual Eubalaena australis from standardized dorsal head drone images, achieving 96.3% and 94.7% rank-1 accuracy.
- Why it matters: Manual catalog matching is slow, and drone-based photo-identification is hard to automate routinely when catalogs are small or expanding without retraining.
- What they did: The study compared two classical similarity methods—HOG and symmetric log-chamfer—using 375 query images from 198 known whales against 411 reference images of known individuals.
- The result: HOG ranked the correct whale first in 361/375 cases and log-chamfer in 355/375; using a risk-score rule to choose the lower-risk method raised rank-1 accuracy to 368/375 (98.1%).
