Abstract
In this paper, we describe a technique to temporally sort
a collection of photos that span many years. By reasoning
about persistence of visible structures, we show how this
sorting task can be formulated as a constraint satisfaction
problem (CSP). Casting this problem as a CSP allows us to
efficiently find a suitable ordering of the images despite the
large size of the solution space (factorial in the number of
images) and the presence of occlusions. We present experimental
results for photographs of a city acquired over a one
hundred year period.
