       In this paper, we present a new Hybrid Hierarchical Clustering
       approach for Image Retrieval. Our method combines features from
       both divisive and agglomerative clustering paradigms in order
       to yield good-quality clustering solutions with reduced
       computational cost. We provide several experiments showing that
       our technique reduces the number of required comparisons to
       perform a retrieval without significant loss in effectiveness
       when compared to flat-based solutions.
