Fast image clustering based on compressed camera fingerprints
作者:
Highlights:
• The algorithm is composed of two stages of clustering: initial and fine clustering.
• The initial clustering stage uses compressed fingerprints which significantly reduces computational cost and memory requirements.
• The fine clustering stage uses average full fingerprints and enhances the quality of clusters.
• The computational complexity of the clustering algorithm is much less than state-of-the-art algorithms on small, medium and large datasets.
• The proposed algorithm is robust to NC≫SC problem i.e., when the number of clusters NC is much larger than size of cluster SC.
