This (ugly) webpage presents a list of references, codes and videolectures available for SMC/particle filters. It is by no means exhaustive and obviously biased towards my work and the work of my close colleagues. A complementary site for SMC and Particle filters resources by Pierre Del Moral can be found here.
I keep on adding stuff from time to time, although not as often as I should.

Fighting degeneracy: Using MCMC steps & look-ahead strategies
A
well-known problem with SMC approximations is that they suffer from the
degeneracy problem, i.e. as time increases the approximations of the
"earlier" marginal distributions collapse. You can try to mitigate (but
not eliminate) this problem using either some MCMC moves as suggested
by Gilks & Berzuini or by using lookahead strategies of which
my favourite is block sampling.

SMC Smoothing
In
the context of state-space models, it is often of interest to perform
smoothing. Standard SMC approximations do provide an estimate of
the joint smoothing distributions but it is poor because of the
degeneracy problem aforementioned. Specific smoothing procedures have
been proposed to address this.

SMC for on-line Bayesian static parameter estimation in state-space models
It is tempting to do on-line Bayesian static parameter estimation in
state-space models using SMC and MCMC moves. Unfortunately, all these
methods suffer from the path degeneracy problems so should be used
cautiously: definitely unreliable for big datasets and/or vague priors.
* P. Fearnhead, MCMC, sufficient statistics and particle filters, JCGS,

moves on static parameters to mitigate the degeneracy problem. It is clearly acknowledged that this does not entirely solve the
problem; see the discussion.

SMC for on-line and batch maximum likelihood inference of static
parameter estimation in state-space models
As
all the SMC procedures for on-line Bayesian inference suffer from the
degeneracy problem, me and my colleagues have tried for many years to
develop alternative methods which bypass this problem. If you accept to
be non-Bayesian about the parameter, this is possible. An earlier
approach we considered consists of
using a pseudo-likelihood, this yields an estimate which is not
statistically efficient but you do not even need particle filters in
this case. Eventually, we have come up with a
forward-only implementation of the forward filtering-backward smoothing
procedure: it is
the key to obtain stable algorithms to perform on-line Maximum
Likelihood (ML) static parameter
estimation in state-space models. For
off-line approaches, all the smoothing approaches described previously
can be and have been used. * C. Andrieu, A.D. & V.B. Tadic, Online EM for parameter
estimation in nonlinear-non Gaussian state-space models, Proc. IEEE

Even if you fixed the random seed in your particle filter, the
resulting simulated likelihood function is discontinuous and can vary
significantly for a moderate number of particles as the resampling step
is a discontinuous operation. Evaluating the MLE by maximizing this
function is thus difficult. For one-dimensional state, M.K. Pitt
proposed a simple and efficient solution to this problem in 2002, just
reorder the particles on the real line and perform a piecewise linear
approximation of the resulting empirical CDF. You obtain a continuous simulated likelihood function.

SMC for batch Bayesian static parameter estimation in state-space models
Obviously
for batch joint Bayesian state and parameter estimation, you can use
MCMC methods. However it can be difficult to design efficient
algorithms. In the context where one can only simulate the latent
process but does not have access to the transition prior, standard MCMC
just fail. SMC can come to the rescue in these scenarios.
* Lee, D.S. & Chia, N.K.K, A particle algorithm for sequential Bayesian parameter estimation and model selection, IEEE Trans. Signal Proc., 2002. -
This paper proposes to use particle filters mixed with MCMC steps. MCMC steps are
used to rejuvenate the whole state sequence and parameter so this is
not an on-line algorithm as the complexity increases over time but can
be used as an alternative to standard MCMC.

Pdf and Particle Markov chain Monte Carlo methods (with discussion), JRSS B, 2010 Pdf -
This paper shows that it is possible to build high-dimensional proposal
distributions for MCMC using SMC, it can be used to develop algorithms
to sample from the joint posterior distribution of states
and parameters. NB: At the 101 level, you can establish the validity of
the particle marginal Metropolis-Hastings on the parameter component from
the unbiasedness of the marginal likelihood estimator. As pointed out
in Section 5.1. of the paper, this is somewhat restrictive and
misleading. In my opinion,
the nicest part of the paper is the conditional SMC/particle Gibbs
sampler bit which does not follow at all from the unbiasedness of
the marginal likelihood estimator.

Introduces a new class of particle filters which can provide
significantly lower variance estimates of the normalizing constant at
the cost of a simple algorithmic modification. It relies on a change of measure on the particle system. SMC as an alternative/complement to MCMC
The
idea of mixing SMC and MCMC to sample from a sequence of distributions
all defined on the same space has appeared independently in various
papers. * G.E. Crooks, Nonequilibrium Measurements of Free Energy Differences for Microscopically Reversible Markovian Systems, J. Stat. Phys., 1998. Pdf -
This paper presents a discrete-time version of the celebrated Jarzynski's equality in
statistical physics (and slight generalization of it) showing that a
sequence of non-homogeneous MCMC kernels "moving" towards a target can
be reweighted using a
clever importance sampling trick based on some reverse Markov kernels to obtain an unbiased estimator of
the normalizing constant and an approximation of the target of
interest. Not quite SMC as no resampling is used.
* W. Gilks & C. Berzuini, Following a Moving Target: Monte Carlo Inference for Dynamic Bayesian Models, JRSS B,
2001 -
This paper proposes to move the particles using MCMC moves with the
appropriate invariant distribution so as to introduce diversity among
particles. It was discussed in the framework of state-space models with
static parameters. If you don't include any state, this gives you a
method for sampling the sequence of posteriors of the parameter. It
also introduces independently the same construction as Crooks based
on a sequence of reverse Markov kernels (this is hidden in the
proof; see Lemma 1 and Corollary 1). * R.M. Neal, Annealed Importance Sampling, Stat. Comp., 2001. Pdf - This paper introduced independently a discrete-time version of the celebrated Jarzynski's equality in
statistical physics based on a sequence of reverse Markov kernels and discusses
carefully some applications to Bayesian inference with a sequence of annealed target distributions.
Not quite SMC as no resampling is used. In this context, increasing the
number of annealed auxiliary target distributions can prevent standard
weights degeneracy.
* N. Chopin, A Sequential Particle Filter Method for Static Models, Biometrika, 2002. -
This paper details a careful application of the resample move algorithm for

Recent Convergence Results of Interest
Besides
Del Moral's books (2004, 2013), here are a few papers of interest
essentially weakening the assumptions in the aforementioned books.
* N. Whiteley, Stability properties of particle filters, Annals Applied Proba, 2013. Pdf - Weak(er) assumptions ensuring uniform convergence of particle filters, requires bounded observations.
* R. Douc, E. Moulines & J. Olsson, Long-term stability of SMC methods under verifiable conditions, Annals Applied Proba, to appear. Pdf - Other weak(er) assumptions ensuring uniform stability of the variance for particle filters.
*
J. Berard, P. Del Moral & A.D., A log-normal central limit theorem
for particle approximations of normalizing constants, Electronic J. Proba, 2014 Pdf. -
Standard CLT for particle methods assume the time horizon T is fixed
and the number N of particles goes to infinity. However, in
practice people usually scale N linearly with T when estimating
normalizing constants/marginal likelihoods. This paper establishes a CLT for the
resulting estimate as T goes to infinity. The normalizing constant estimate divided
by the true normalizing constant converges towards a log-normal
distribution.
What about SMC in high dimensional spaces?
* R. Van Handel, Can particle filters beat the curse of dimensionality? Pdf - Answer is yes if you are ready to accept some bias but current assumptions to ensure this are extremely strong, or no bias but the rate of convergence is slowler than the usual Monte Carlo rate.
