2. Part 2 (p 11-15)
3. Conclusion (p 16)

3.

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

4.

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

5.

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

7.

MOCAP OVER TIME
Open up a new
world

8.

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

9.

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

12.

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

13.

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

14.

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

15.

ROBUST MODEL-BASED MOTION TRACKING
THROUGH THE INTEGRATION OF SEARCH
(Lowe, D.G)
AND ESTIMATION
• 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.

16.

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