Live Video Synth

Application of Photosynth

Mapping by geo-tagging data.

Navigation

Augmented Reality

Explore the model to check for any

Damage

Virtual Earth

“We have a real world outside

the window, but it will be

unprecedented if you can feel it

in Microsoft Windows!!!”

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

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

Deep zoom Technology

DZI file format(.xml/.dzi)

Platforms: AJAX and XAML

Sparse Images

Why Deep Zoom is Fast?

Deep Zoom Algorithm

70 Giga Pixel Image

First level of Zoom

2nd Level of Zoom

3rd Level of Zoom

Deep Zoom Advanced

Applications of Deep Zoom

Google Earth

Universe Navigation

World wide Telescope

Environment for newspapers and

magazines

Human can understand the real

meaning of picture

“A Picture May Tell A Thousand Words,

But How Many Of Those Words Are Fair And True?”
