===============================
Dense DAISY feature description
===============================

The DAISY local image descriptor is based on gradient orientation histograms
similar to the SIFT descriptor. It is formulated in a way that allows for fast
dense extraction which is useful for e.g. bag-of-features image
representations.

In this example a limited number of DAISY descriptors are extracted at a large
scale for illustrative purposes.
