FALKOLib is a library containing keypoint detectors for the stable detection
of interest points in laser measurements and two descriptors for robust associations.

Long Description
Detecting features in sensor measurements and distinguishing among
them is an important capability for robot localization and navigation.
Despite the wide diffusion of range finders, there are few works
on keypoint features for 2D LIDAR and there is potential for improvement
over the existing methods.
We propose two novel keypoint detectors for the stable detection of
interest points in laser measurements (named FALKO and OC)
and two descriptors for robust associations (named BSC and CGH).
The features defined by combining keypoints and descriptors allow
stable and efficient place recognition.

Input Data
The approach takes raw laser range data.
Laser scans with higher resolution (0.25 deg) enables richer description of the environment.
Odometry can be used for testing the association between features
Logfile Format
Carmen log format. Raw scan data.
Type of Map
feature maps
Hardware/Software Requirements
Developed and tested under Linux (tested with GCC>= 4.8).
Library dependencies: Eigen 3.0, Boost.
CMake is needed for building.
