2. Visual Technology
 Deals with pictures, and videos
 E.g. POV, Infrared, Laser, LEDs,
Famto photography, Sea-dragon
Technology, 3D, HD, etc.

3. Sea-dragon Technology
 Founder Blaise Agüera y Arcas (2003)
 Named after team in Microsoft Live
Labs
 Graphics and Photos smoothly
browsed
 Microsoft Silverlight, Photosynth,
Pivot and Deep Zoom Composer

4. Photosynth
 Open Source Software
 Augmented Reality
 Generates a 3D Panorama from 2D
photos
 Point cloud
 Online Sharing

5. Photosynth

6. How does Photosynth work?
 Adding 2D Images (20-300)
 Identifying features
 Matching features across photographs
 Image Segmantation
 Assembly into 3D space

7. Photosynthing a Small Object

8. Capture images from maximum
possible angle

9. Importing images to
Photosynth

10. 2D view

11. 3D Panorama

12. Point Cloud

13. Sharing Photosynths
 Provides Direct Link to your Synth
 Embed Photosynth Viewer in
Webpage

14. Live Video Synth

15. Application of Photosynth
 Mapping by geo-tagging data.
 Navigation
 Augmented Reality
 Explore the model to check for any
Damage
 Virtual Earth

16. “We have a real world outside
the window, but it will be
unprecedented if you can feel it
in Microsoft Windows!!!”

17. Limitations of Photosynth
(In Present version)
 Synth can’t be downloaded to disk
(Data stored remotely)
 Limitation of storage on server
 Computer may crunch, when images
are more than 600

18. Deep Zoom Composer (DZC)
 Continuous zoom in and out
 Panning through Images
 100 MP image take longer to operate
 Deep zoom algorithm reduces the
time
 DZC can operate 4 billion pixels very
quickly

19. Deep zoom Technology
 DZI file format(.xml/.dzi)
 Platforms: AJAX and XAML
 Sparse Images

20. Why Deep Zoom is Fast?
Deep Zoom Algorithm

21. 70 Giga Pixel Image

22. First level of Zoom

23. 2nd Level of Zoom

24. 3rd Level of Zoom

25. Deep Zoom Advanced
Codeing
XAML (Adding Interactivity to DZI)
<MultiScaleImage
x:Name="deepZoomObject"
Source="source/dzc_output.xml"
MouseEnter="DeepZoomObject_Mou
seEnter" />

26. Applications of Deep Zoom
 Google Earth
 Universe Navigation
 World wide Telescope
 Environment for newspapers and
magazines
 Human can understand the real
meaning of picture

27. “A Picture May Tell A Thousand
Words,
But How Many Of Those Words Are
Fair And True?”
