Query: Human Re-identification by Matching Compositional Template with Cluster
  Sampling   This paper aims at a newly raising task in visual surveillance:
re-identifying people at a distance by matching body information, given several
reference examples. Most of existing works solve this task by matching a
reference template with the target individual, but often suffer from large
human appearance variability (e.g. different poses/views, illumination) and
high false positives in matching caused by conjunctions, occlusions or
surrounding clutters. Addressing these problems, we construct a simple yet
expressive template from a few reference images of a certain individual, which
represents the body as an articulated assembly of compositional and alternative
parts, and propose an effective matching algorithm with cluster sampling. This
algorithm is designed within a candidacy graph whose vertices are matching
candidates (i.e. a pair of source and target body parts), and iterates in two
steps for convergence. (i) It generates possible partial matches based on
compatible and competitive relations among body parts. (ii) It confirms the
partial matches to generate a new matching solution, which is accepted by the
Markov Chain Monte Carlo (MCMC) mechanism. In the experiments, we demonstrate
the superior performance of our approach on three public databases compared to
existing methods.
