"The main focus of expansion for LG is India, not China".
In San Juan, a 30-minute drive to the west, the airport is expected to get an upgrade and JetBlue has deemed it a "focus" of expansion, making travel to the island from the East Coast even easier.
The approach is based on the FOE (focus of expansion) concept, but it takes a somewhat unconventional route.
The robot undergoes translation along (Z_e) with a velocity (V = -frac{delta Z}{delta t}) over a distance (Delta z = z_2 - z_1), approaching the focus of expansion (FOE).
The DRIVE system uses a qualitative scene model and a fuzzy focus of expansion to estimate robot motion from visual cues, to detect and track moving objects, and to construct and maintain a global dynamic reference model.
For both the focus of expansion in the first video and the bus in the second video, CWD recorded more fixations, whereas the Con group recorded more fixations than CWD on the bus stop in the first video scenario.

The complexity of the process is increased by the fact that the camera is also moving, because all objects in the image sequence seem to move away from a given point, the focus of expansion (FOE), and there is no static object that can be used as a reference.
end{aligned} (4 For a point N, on the obstacle, the distance from its projection, p1, on an image plane to the focus of expansion ({y_{s_{1}}}) and length of the optical flow vector (frac{delta {y_{s_{1}}}}{delta t}) are required to estimate the time-to-contact Eq. 4.
For example, in a pattern expanding at a constant velocity, each feature accelerates centrifugally such that its speed is proportional to its distance from the focus of expansion.
