This is a template library for particle filtering. Templated abstract base classes for different particle filters are provided (e.g. the Bootstrap Filter, the SISR filter, the Auxiliary Particle Filter, the Rao-Blackwellized particle filter), as well as non-abstract (but indeed templated) base classes for closed-form filtering algorithms (e.g. Kalman Filter, Hidden Markov Model filter, etc.).

Once you have a certain model in mind, all you have to do is make it into a class that inherits from the filter you want to use.

Dependencies

This code makes use of the following libraries:

Also, your compiler must enable C++17.

Installation

Option 1: Install with <tt>CMake</tt>

git clone this Github repostory, cd into the directory where everything is saved, then run the following commands:

mkdir build && cd build/
cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr/local
sudo cmake --build . --config Release --target install --parallel

You may subsitute another directory for /usr/local, if you wish. This will also build unit tests that can be run with the following command (assuming you're still in build/):

./test/pf_test

Note: for this to method work, you will need to install Catch2 "system wide" so that its *.cmake files are installed as well. To do this, click here.

Option 2: Drag-and-drop <tt>.h</tt> files

This is a header-only library, so there will be no extra building necessary. If you just want to copy the desired header files from include/pf into your own project, and build that project by itself, that's totally fine. There is no linking necessary, either. If you go this route, though, make sure to compile with C++17 enabled. Note, also, that this code all makes use of Eigen v3.3 and Boost v1.65.1. Unit tests use the Catch2 library.

Examples

Don't know how to use this? No problem. Check out the examples sub-directory. This is a stand-alone cmake project, so you can just copy this sub-directory anywhere you like, and start editing.

For example, copy to Desktop and have at it:

cp -r ~/pf/examples/ ~/Desktop/
cd Desktop/examples/
mkdir build && cd build
cmake ..
make

If there are no error messages, you will have an executable named pf_example in that same directory. Running it without command line arguments will prompt you for arguments and tell you how it can be used.
