Furthermore, although we can roughly follow the movement of features at the velocities derived for each filter, traceability is not good everywhere, and it appears that the temporal change of radiance features is not always characterized by simple advection.
For example, by acquiring sequential frames at 90° with respect to each other, it should be possible to track the movement of features such as myeloid cells with a time-lapse resolution movement determined by the time needed to acquire the (~2-4) orthogonal images required to calculate the 3-D coordinates of the moving features.
Software tracks the movement of facial features and classifies them using a coding system developed by the psychologist Paul Ekman, which is then correlated with a second taxonomy of emotional states created by the Cambridge autism researcher (and Ali G cousin) Simon Baron-Cohen.
To be more robust and to take into account the local movement of image features, Wang et al. [13] introduce dense trajectories of keypoints.
DVC relies on tracking the movement of microstructural features, and as such, the accuracy and precision of this technique may depend on trabecular structure.
By tracking the movement of surface features on the flowing ice, the team was able to estimate the speeds for 178 of the island's largest glaciers for the winters of 2000 and 2005, and for 195 of them for the winters of 2006 through 2010.
We note, however, that (FLIM) OPT, can potentially provide information with much higher time-lapse resolution than the total data acquisition time by tracking the movement of sample features.
Tracking of the movements of blocky features will also yield wind vectors covering both dayside and nightside.
The rate of rotation can be measured from the spectrum of the star, or by timing the movements of active features on the surface.
This curiosity led him to a study of the flight of birds, the movement of water, the features of the land, the mechanical advantage obtainable in gears and gear trains, the growth of plants, the anatomy of man, and many other things.
"Forgiveness/Mourning," an unusually stimulating program that the Asia Society calls an "evening of movement theater" features two sets of leading experimental artists dealing with themes of war or loss.
