What is Motion tracking(mocap)?
The process of recording the movement of objects or people

How it works?
Images from multiple cameras to calculate 3D positions

WHEN AND WHERE
WAS CREATED?
In the 1980s, there was a growth in the study of human motion in biomechanics labs. Tom Calvert, a professor of kinesiology and computer science at Simon Fraser University was one of the first to use potentiometers to track knee flexion and extension.

How does mocap make life easier?
Reduces time spent

MOCAP OVER TIME
Open up a new world

ENVIRONMENTAL EFFECT
Non-biodegradable compounds as plastic (VR)
Carbon dioxide emissions during transportation and manufacturing

SOCIAL EFFECT
More satisfied people

Motion Tracking with an Active Camera (Murray D. & Basu A..)
A goals of this article is determine a moving object at the same time with pan or tilt camera
He used some formula to calculate pixel position
Any noise of image that interferes to work and With morphological filtering editors can suppress some noise of image

Motion Tracking: No Silver Bullet, but a Respectable Arsenal
(Greg Welch, Eric Foxlin)
Figure out the multitasking of this technology
Gave examples from life where this technology is used
Created app to combine all functions of mocap

STRATEGIES FOR MOTION TRACKING
AND CORRECTION IN PET (RAHMIM,A.&ROUSSET,O.& ZAIDI,H.)
Expand closed frames to treat respiratory cycle
Own approach to problem detection using embedded algorithms
Considering all the complexities of the brain, find out that more information and time is given
in space

HUMAN MOTION TRACKING FOR REHABILITATION—A SURVEY (ZHOU, H.& HU, H.)
Dealing with a problem in a narrow one requires every possible effort,
Need big skill to work with this sphere
They are analyzed those technology
Created application that have good design and contain functions which edit videos or create characters move

ROBUST MODEL-BASED MOTION TRACKING THROUGH THE INTEGRATION OF SEARCH
AND ESTIMATION
(Lowe, D.G)
Find more correct way to integrate an image into computer code
He tested this methods on 1000 images and move it very slowly
Mistakes with tracking will be less.

CONCLUSION
All articles was about improve the mocap
They all used some algebra methods
Present applications based on they’re findings
