SIFT feature detector and GLOH descriptor extractor.

Detects features using the Scale Invariant Feature Transform (SIFT), by David Lowe. Descriptors are extracted using Gradient Location and Orientation Histogram (GLOH).

WARNING: Although GLOH is free of patents, the SIFT algorithm, used to detect features that will later be used by GLOH descriptors, is patented by the University of British Columbia, before using it, make sure you have the appropriate permission to do so.
