Package Description

This package contains a recent version of the Bayesian Filtering Library (BFL), distributed by the Orocos Project. For stability reasons, this package is currently locked to revision 31655 (April 19, 2010), but this revision will be updated on a regular basis to the latest available BFL trunk. This ROS package does not modify BFL in any way, it simply provides a convenient way to download and compile the library, because BFL is not available from an OS package manager. This ROS package compiles BFL with the Boost library for matrix operations and random number generation.

This library encoporates ideas from several available software
libraries:

- Scene (Andrew Davison).  See
<http://www.robots.ox.ac.uk/~ajd/Scene/>

- Bayes++ (from ACFR). See
<http://www.acfr.usyd.edu.au/technology/bayesianfilter/Bayes++.htm> 

- The CES programming library (Sebastian Thrun).  See 
<http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/thrun/public_html/papers/thrun.ces-tr.html>

- Our own research with Bayesian methods for compliant motion problems
<http://www.mech.kuleuven.be/pma/research/manip/default_en.phtml>

It's most important features are:
- Released under the GNU LGPL licence
- Wrapper around matrix and RNG libraries, so you can use your own
  favourite matrix library.
  At 2004/03/02 wrappers exist for
  =================================================
  * The matrix/RNG wrapper library of LTIlib
  <http://ltilib.sourceforge.net/doc/homepage/index.shtml>: a library
  with algorithms and data structures frequently used in image
  processing and computer vision.

  * NEWMAT <http://www.robertnz.net/nm_intro.htm> Matrix Library
  =================================================
  * boost <http://www.boost.org/> RNG


- "Bayesian unifying Design".  This allows to incorporate any Bayesian
  filtering algorithm!

  Currently the following filter schemes are implemented.
  * Standard KF, EKF, IEKF and Non-minimal State KF (See
  <http://people.mech.kuleuven.ac.be/~tlefebvr/publicaties/BayesStat.ps.gz> 

  * Standard Particle filter (arbitrary proposal), BootstrapFilter
  (Proposal = System Model PDF), Auxiliary Particle filter, Extended
  Kalman Particle Filter. 

For further details about the design ideas, see the poster about the
library presented at Valencia 7, a conference about Bayesian
Statistics, available from
<http://people.mech.kuleuven.ac.be/~kgadeyne/doctoraat.html>

    Lots of changes to improve performance of particle filters and to
    allow the use of hybrid states:
    * Replace std::list<> by std::vector<> to increase performance of
    particle filters.
    * Pass various arguments as reference to eliminate unnecessary
    copies (especially of std::vector<> types containling long lists
    of samples).
    * C++-ify the Sample class.
    * Remove template code that was specifically written for
    ColumnVector type, and replace by template specialization where
    necessary.
    * Fix in Probability class to allow probability of zero.

2005-05-19  Klaas Gadeyne  <first dot last at gmail dot com>

    * Bring Ginac classes for symbolic derivation back in sync with

    * release 0.0.1-pre3
    * Redesigned conditionalgaussian class (bad design, introduced
    coupling)
    * Eliminated some classes that had become superfluous due to the
    template classes (eg. analyticpdf, linearanalyticpdf, etc)
    * Fully rewrote systemmodel and measurementmodel to eliminate
    coupling (this coupling was due to bad design of
    conditionalgaussian class)

2002-10-22  Klaas Gadeyne  <klaas dot gadeyne at mech dot kuleuven dot ac dot be>

    * Converted all base-classes into template ones, allowing for more

Package Description

This package contains a recent version of the Bayesian Filtering Library (BFL), distributed by the Orocos Project. For stability reasons, this package is currently locked to revision 31655 (April 19, 2010), but this revision will be updated on a regular basis to the latest available BFL trunk. This ROS package does not modify BFL in any way, it simply provides a convenient way to download and compile the library, because BFL is not available from an OS package manager. This ROS package compiles BFL with the Boost library for matrix operations and random number generation.

This library encoporates ideas from several available software
libraries:

- Scene (Andrew Davison).  See
<http://www.robots.ox.ac.uk/~ajd/Scene/>

- Bayes++ (from ACFR). See
<http://www.acfr.usyd.edu.au/technology/bayesianfilter/Bayes++.htm> 

- The CES programming library (Sebastian Thrun).  See 
<http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/thrun/public_html/papers/thrun.ces-tr.html>

- Our own research with Bayesian methods for compliant motion problems
<http://www.mech.kuleuven.be/pma/research/manip/default_en.phtml>

It's most important features are:
- Released under the GNU LGPL licence
- Wrapper around matrix and RNG libraries, so you can use your own
  favourite matrix library.
  At 2004/03/02 wrappers exist for
  =================================================
  * The matrix/RNG wrapper library of LTIlib
  <http://ltilib.sourceforge.net/doc/homepage/index.shtml>: a library
  with algorithms and data structures frequently used in image
  processing and computer vision.

  * NEWMAT <http://www.robertnz.net/nm_intro.htm> Matrix Library
  =================================================
  * boost <http://www.boost.org/> RNG


- "Bayesian unifying Design".  This allows to incorporate any Bayesian
  filtering algorithm!

  Currently the following filter schemes are implemented.
  * Standard KF, EKF, IEKF and Non-minimal State KF (See
  <http://people.mech.kuleuven.ac.be/~tlefebvr/publicaties/BayesStat.ps.gz> 

  * Standard Particle filter (arbitrary proposal), BootstrapFilter
  (Proposal = System Model PDF), Auxiliary Particle filter, Extended
  Kalman Particle Filter. 

For further details about the design ideas, see the poster about the
library presented at Valencia 7, a conference about Bayesian
Statistics, available from

2005-06-02  Wim Meeussen  <first dot last at mech dot kuleuven dot ac dot be>

    Lots of changes to improve performance of particle filters and to
    allow the use of hybrid states:
    * Replace std::list<> by std::vector<> to increase performance of
    particle filters.
    * Pass various arguments as reference to eliminate unnecessary
    copies (especially of std::vector<> types containling long lists
    of samples).
    * C++-ify the Sample class.
    * Remove template code that was specifically written for
    ColumnVector type, and replace by template specialization where
    necessary.
    * Fix in Probability class to allow probability of zero.

2005-05-19  Klaas Gadeyne  <first dot last at gmail dot com>

    * Bring Ginac classes for symbolic derivation back in sync with

    :).  Added code for the Auxiliary filter, seems to work fine.  No
    performancetests yet.
    * cvs tag rel-0_4_1-pre1

    * Reworked filter polymorphism implementation.  Should be far more
    clear now.
    * Added IEKF test to test_switch_kf_bootstrapfilter.cpp and
    consequently renamed to test_compare_filters.cpp
    * Preparation for ASIR filter algorithm

2004-06-07  Klaas Gadeyne  <klaas dot gadeyne at mech dot kuleuven dot ac dot be>

    version of newmat and scythe for this.
    * Rename ORO stuff (oroerr.h etc) into BFL
    * Give constant.h bfl_ prefix
    * cvs tag rel-0_4_0-rc2

Package Description

This package contains a recent version of the Bayesian Filtering Library (BFL), distributed by the Orocos Project. For stability reasons, this package is currently locked to revision 31655 (April 19, 2010), but this revision will be updated on a regular basis to the latest available BFL trunk. This ROS package does not modify BFL in any way, it simply provides a convenient way to download and compile the library, because BFL is not available from an OS package manager. This ROS package compiles BFL with the Boost library for matrix operations and random number generation.

This library encoporates ideas from several available software
libraries:

- Scene (Andrew Davison).  See
<http://www.robots.ox.ac.uk/~ajd/Scene/>

- Bayes++ (from ACFR). See
<http://www.acfr.usyd.edu.au/technology/bayesianfilter/Bayes++.htm> 

- The CES programming library (Sebastian Thrun).  See 
<http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/thrun/public_html/papers/thrun.ces-tr.html>

- Our own research with Bayesian methods for compliant motion problems
<http://www.mech.kuleuven.be/pma/research/manip/default_en.phtml>

It's most important features are:
- Released under the GNU LGPL licence
- Wrapper around matrix and RNG libraries, so you can use your own
  favourite matrix library.
  At 2004/03/02 wrappers exist for
  =================================================
  * The matrix/RNG wrapper library of LTIlib
  <http://ltilib.sourceforge.net/doc/homepage/index.shtml>: a library
  with algorithms and data structures frequently used in image
  processing and computer vision.

  * NEWMAT <http://www.robertnz.net/nm_intro.htm> Matrix Library
  =================================================
  * boost <http://www.boost.org/> RNG


- "Bayesian unifying Design".  This allows to incorporate any Bayesian
  filtering algorithm!

  Currently the following filter schemes are implemented.
  * Standard KF, EKF, IEKF and Non-minimal State KF (See
  <http://people.mech.kuleuven.ac.be/~tlefebvr/publicaties/BayesStat.ps.gz> 

  * Standard Particle filter (arbitrary proposal), BootstrapFilter
  (Proposal = System Model PDF), Auxiliary Particle filter, Extended
  Kalman Particle Filter. 

For further details about the design ideas, see the poster about the
library presented at Valencia 7, a conference about Bayesian
Statistics, available from

    Lots of changes to improve performance of particle filters and to
    allow the use of hybrid states:
    * Replace std::list<> by std::vector<> to increase performance of
    particle filters.
    * Pass various arguments as reference to eliminate unnecessary
    copies (especially of std::vector<> types containling long lists
    of samples).
    * C++-ify the Sample class.
    * Remove template code that was specifically written for
    ColumnVector type, and replace by template specialization where
    necessary.
    * Fix in Probability class to allow probability of zero.

Package Description

This package contains a recent version of the Bayesian Filtering Library (BFL), distributed by the Orocos Project. For stability reasons, this package is currently locked to revision 31655 (April 19, 2010), but this revision will be updated on a regular basis to the latest available BFL trunk. This ROS package does not modify BFL in any way, it simply provides a convenient way to download and compile the library, because BFL is not available from an OS package manager. This ROS package compiles BFL with the Boost library for matrix operations and random number generation.

This library encoporates ideas from several available software
libraries:

- Scene (Andrew Davison).  See
<http://www.robots.ox.ac.uk/~ajd/Scene/>

- Bayes++ (from ACFR). See
<http://www.acfr.usyd.edu.au/technology/bayesianfilter/Bayes++.htm> 

- The CES programming library (Sebastian Thrun).  See 
<http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/thrun/public_html/papers/thrun.ces-tr.html>

- Our own research with Bayesian methods for compliant motion problems
<http://www.mech.kuleuven.be/pma/research/manip/default_en.phtml>

It's most important features are:
- Released under the GNU LGPL licence
- Wrapper around matrix and RNG libraries, so you can use your own
  favourite matrix library.
  At 2004/03/02 wrappers exist for
  =================================================
  * The matrix/RNG wrapper library of LTIlib
  <http://ltilib.sourceforge.net/doc/homepage/index.shtml>: a library
  with algorithms and data structures frequently used in image
  processing and computer vision.

  * NEWMAT <http://www.robertnz.net/nm_intro.htm> Matrix Library
  =================================================
  * boost <http://www.boost.org/> RNG


- "Bayesian unifying Design".  This allows to incorporate any Bayesian
  filtering algorithm!

  Currently the following filter schemes are implemented.
  * Standard KF, EKF, IEKF and Non-minimal State KF (See
  <http://people.mech.kuleuven.ac.be/~tlefebvr/publicaties/BayesStat.ps.gz> 

  * Standard Particle filter (arbitrary proposal), BootstrapFilter
  (Proposal = System Model PDF), Auxiliary Particle filter, Extended
  Kalman Particle Filter. 

For further details about the design ideas, see the poster about the
library presented at Valencia 7, a conference about Bayesian
Statistics, available from

    allow the use of hybrid states:
    * Replace std::list<> by std::vector<> to increase performance of
    particle filters.
    * Pass various arguments as reference to eliminate unnecessary
    copies (especially of std::vector<> types containling long lists
    of samples).

Package Description

This package contains a recent version of the Bayesian Filtering Library (BFL), distributed by the Orocos Project. For stability reasons, this package is currently locked to revision 31655 (April 19, 2010), but this revision will be updated on a regular basis to the latest available BFL trunk. This ROS package does not modify BFL in any way, it simply provides a convenient way to download and compile the library, because BFL is not available from an OS package manager. This ROS package compiles BFL with the Boost library for matrix operations and random number generation.

This library encoporates ideas from several available software
libraries:

- Scene (Andrew Davison).  See
<http://www.robots.ox.ac.uk/~ajd/Scene/>

- Bayes++ (from ACFR). See
<http://www.acfr.usyd.edu.au/technology/bayesianfilter/Bayes++.htm> 

- The CES programming library (Sebastian Thrun).  See 
<http://www-2.cs.cmu.edu/afs/cs.cmu.edu/user/thrun/public_html/papers/thrun.ces-tr.html>

- Our own research with Bayesian methods for compliant motion problems
<http://www.mech.kuleuven.be/pma/research/manip/default_en.phtml>

It's most important features are:
- Released under the GNU LGPL licence
- Wrapper around matrix and RNG libraries, so you can use your own
  favourite matrix library.
  At 2004/03/02 wrappers exist for
  =================================================
  * The matrix/RNG wrapper library of LTIlib
  <http://ltilib.sourceforge.net/doc/homepage/index.shtml>: a library
  with algorithms and data structures frequently used in image
  processing and computer vision.

  * NEWMAT <http://www.robertnz.net/nm_intro.htm> Matrix Library
  =================================================
  * boost <http://www.boost.org/> RNG


- "Bayesian unifying Design".  This allows to incorporate any Bayesian
  filtering algorithm!

  Currently the following filter schemes are implemented.
  * Standard KF, EKF, IEKF and Non-minimal State KF (See
  <http://people.mech.kuleuven.ac.be/~tlefebvr/publicaties/BayesStat.ps.gz> 

  * Standard Particle filter (arbitrary proposal), BootstrapFilter
  (Proposal = System Model PDF), Auxiliary Particle filter, Extended
  Kalman Particle Filter. 

For further details about the design ideas, see the poster about the
library presented at Valencia 7, a conference about Bayesian
Statistics, available from

    Lots of changes to improve performance of particle filters and to
    allow the use of hybrid states:
    * Replace std::list<> by std::vector<> to increase performance of
    particle filters.
    * Pass various arguments as reference to eliminate unnecessary
    copies (especially of std::vector<> types containling long lists
    of samples).
    * C++-ify the Sample class.
    * Remove template code that was specifically written for
    ColumnVector type, and replace by template specialization where
    necessary.
    * Fix in Probability class to allow probability of zero.

2005-05-19  Klaas Gadeyne  <first dot last at gmail dot com>

    * Bring Ginac classes for symbolic derivation back in sync with

    * Update Use new config file generated by matrix wrapper. Now you
    only need to specify--with-matrix_wrapper=/path and not
    --with-newmat=/path or --with-lti=/path 

2004-12-09  Klaas Gadeyne  <klaas dot gadeyne at mech dot kuleuven dot ac dot be>

    Resample() and ResampleStep in particlefilter class.  + add some
    "static" to params.
    * src/filter/particlefilter.cpp (ProposalStepInternal): Important

    coupling)
    * Eliminated some classes that had become superfluous due to the
    template classes (eg. analyticpdf, linearanalyticpdf, etc)
    * Fully rewrote systemmodel and measurementmodel to eliminate
    coupling (this coupling was due to bad design of
