Motivation:

• Local features [28,7,64,39,34], comprise descriptors and geometry information about specific image regions; they are especially useful to match images depicting rigid objects.

• The score provided by local feature-based geometric verification usually reflects image similarity well, being more reliable than global feature distance.
