Description
Motion tracking or motion capture started as a photogrammetric analysis tool
in biomechanics research in the 1970s and 1980s, and expanded into education,
training, sports and recently computer animation for television, cinema, and
video games as the technology matured. A performer wears markers near each
joint to identify the motion by the positions or angles between the markers.
Acoustic, inertial, LED, magnetic or reflective markers, or combinations of any
of these, are tracked, optimally at least two times the frequency rate of the
desired motion, to submillimeter positions. The resolution of the system is
important in both the spatial resolution and temporal resolution as motion blur
causes almost the same problems as low resolution.

INTER-PROCESS COMMUNICATION OR PROCESS SYNCHRONIZATION
Trending!
Concurrent access to shared data may result in data
inconsistency. Maintaining data consistency requires mechanisms to ensure the orderly execution of cooperating processes. Suppose that we wanted to provide a solution to the consumer-producer problem that fills all the buffers.

PROCESS SCHEDULING:
Trending!
CPU is always busy in Multiprogramming. Because CPU switches from one job to another job. But in simple computers CPU sit idle until the I/O request granted. Scheduling is an important OS function. All resources are scheduled before use.(cpu, memory, devices…..) Process scheduling is an essential part of a Multiprogramming operating systems. Such operating systems allow more than one process to be loaded into the executable memory at a time and the loaded process shares the CPU using time multiplexing
