Make the impossible possible. Change your perspective.
Lytro's newest light field capability, Perspective Shift, allows you
to interactively change your point of view in a picture, after
you’ve taken the picture. On a computer or mobile device,
you can shift the living picture in any direction; left, right, up,
down and all around.
Perspective Shift works on light field pictures you've previously
taken and with any new pictures you take. Change your
perspective and see the moment come alive.

How to start?
Come equipped with good programming skills and
read Wikis in link depths
Several Open Source Projects and Free SDKs to help
you viz. OpenCV, DL, ML, OpenNLP, OpenNI,
OpenTLD, Tesseract for OCR, OpenCL, CUDA for
NVIDIA, etc.
Get started with tutorials and examples
Ask exact doubts after having tried solving the
problem (from what I've seen, people do not help
you online if they don't feel you've tried enough) in
specific fora and open fora like StackOverFlow

@MUGLIKAR 36
Conclusion
You are now a different person than you were a few hours
ago! :)
You'll certainly be more wise and knowledgable after this
workshop, provided you apply what you learn here.
Join the FB/G+ Group – I love Computer Vision – if you liked
this presentation and wish to have continuous interaction with
me and other CV Enthusiasts.
