abstract = {In this paper, Image-time correlation is a beneficial
technique to apply various applications of dynamical events,
where temporal changes of positions of particles (or
objects) can be quantified, constructed by the collection of
time-resolved video data. With the fast development of
camera technologies and imaging softwares, the optimization
of time-binning and spatial-resolution are much
friendly-used for the imaging analysis. Time-dependent
different regions of interest (ROIs) can be chosen, such
that the time resolution of subsequent images should be at
least 10 times faster than the actual dynamical events. Then
time-correlation function will be calculated by the 2d
intensity-intensity correlation of an each pixel-pixel of
individual time frame of image, and the initial slope of
correlation function gives a characteristic time scale that
measures the average magnitude of particle velocities within
the field-of-view. The advantage of image-time correlation
is easy to implement as compared to the PIV (particle
imaging velocimetry). In this short proceeding, the
performance of image-time correlation is highlighted through
a number of applications; such as the slowing down behaviors
of collective dynamics of orientation textures,
dimer-oscillations in rod-networks, and clay (platelet)
migrations in an oil-water droplet. In each system, the
interpretation of image-time correlation is addressed, based
on the experimental observations.},
