New method uses sliced Wasserstein embeddings for color-scheme search

A new method for searching paintings by color scheme has been developed, utilizing sliced Wasserstein embeddings and Hierarchical Navigable Small World (HNSW) graphs. This approach addresses the computational expense of exact Earth Mover's Distance calculations for large datasets. The system projects colors onto multiple directions, averages them into quantiles, and uses L1 distance as a proxy for true Wasserstein distance, achieving high recall rates. AI

IMPACT This research could improve the efficiency and accuracy of image retrieval systems, particularly for datasets with complex feature distributions like color palettes.
