On the use of supervised features for unsupervised image categorization: An evaluation ?
We compared high- and low-level features for unsupervised image categorization. We verified that high-level features significantly outperform low-level features. We assessed how much the performance depends on the dimensionality of the feature vectors. We verified that a simple clustering on supervised features outperform strategies specifically designed for this task.
