GFM stands for General Feature Matching. It defines several concepts:

• feature extractors
• feature descriptors

Two algorithms can be used to match the features:

• The simple matcher is based on descriptors strong distance.
• The group matcher first considers descriptors weak distance and geometric contraints in the group of features, and then confirms the matches with the descriptors strong distance.

History

• 0.1 (2006-04-24) - Initial version
• 0.5 (2011-03-29) - Using templates, added a Lowe style matcher and a CamShift tracker

Tcl interface (generated by swig)

The interface of the module is generated from the following files:

• gfm.i defines the wrapped classes and functions,
• gfmException.i defines the try { } catch block for this module.
