orientation [74]. In the limit, matching a large number of spatial features is
similar to performing template matching [11, 18].
Rather than finding the optimal match for each particle on a frame-by-frame
basis, the temporal association problem can also be solved in a more global
fashion. Such an approach is especially favorable in more complex situations of
incomplete or ambiguous data. For example, particles may temporarily disap-
pear, either because they move out of focus for some time or (as in the case of
quantum dots) because the fluorescence of the probe is intermittent. For single
or well-spaced particles, this problem has been solved by translating the tracking
task into a spatiotemporal segmentation task and finding optimal paths through
the ...
