Tech “Push” vs Market “Pull”
Why
How
Problem
Solution
• Refining a business idea is iterating between “what you can do (the How)” and “what’s most worth doing (the Why)”
• Converging top-down and bottom-up thinking

Camera Culture Creating new ways to capture and share visual information
MIT Media Lab Ramesh Raskar
http://cameraculture.info
Facebook.com/cameraculture
1.Light-Field Camera A new camera design
exploiting the fundamental
dictionary of light-fields for a
single-capture capture of
light-fields with full-
resolution refocusing
effects.
2. Color Primaries A new camera design with
switchable color filter arrays
for optimal color fidelity and
picture quality on scene
geometry, color and
illumination.
3. Flutter-Shutter A camera that codes the
exposure time with a binary
pseudo-sequence to de-
convolve and remove
motion blur in textured
backgrounds and partial
occluders.
4. Compressive
Capture We analyze the gamut of
visual signals from low-
dimensional images to light-
fields and propose non-
adaptive projections for
efficient sparsity exploiting
reconstruction.
Computational Photography
1. Looking around corners Using short laser pulses and fast detector, we
aim to build a device that can look around
corners with no imaging device in the line of
sight using time resolved transient imaging.
2. Reflectance Recovery We demonstrate a new technique that allows
a camera to rapidly acquire reflectance
properties of objects 'in the wild' from a single
viewpoint, over relatively long distances and
without encircling equipment.
3. Trillion Frames per Second Imaging A camera fast enough to capture light pulses
moving through objects. We can use such a
camera to understand reflectance, absorption
and scattering properties of materials.
Femtosecond Imaging 3D Displays
1. Tensor Display A family of compressive light
field displays comprising all
architectures employing a stack
of time-multiplexed, light-
attenuating layers illuminated by
uniform or directional
backlighting
2. Layered 3D Tomographic techniques for
image synthesis on displays
composed of compact volumes
of light-attenuating material.
Such volumetric attenuators
recreate a 4D light field or high-
contrast 2D image when
illuminated by a uniform
backlight.
3. Glasses-free 3D HDTV Light field displays with
increased brightness and
refresh rate by stacking a pair of
modified LCD panels, exploiting
rank and constraint of 3D
displays
4. BIDI Screen A thin, depth-sensing LCD for
3D interaction using light fields
which supports both 2D multi-
touch and unencumbered 3D
gestures.
5. Living Windows 6D
Display A completely passive display
that responds to changes in
viewpoint and changes in
incident light conditions.

1. Augmented Light Fields Expands light field representations
to describe phase and diffraction
effects by using the Wigner
Distribution Function
2. Hologram v Parallax Barrier Defines connections between
parallax barrier displays and
holographic displays by analyzing
their operations and limitations in
phase space
3. Ray–Based Diffraction Model Simplified capture of diffraction

heterodyning.
6. Second Skin Using 3D motion tracking with real-
time vibrotactile feedback aids the
correct of movement and position
errors to improve motor learning.
Health & Wellness
1. Bokode Low-cost, passive optical design
so that bar codes can be shrunk
to fewer than 3mm and read by
ordinary cameras several meters
away.
2. Specklesense Set of motion-sensing
configurations based on laser
speckle sensing . The underlying
principles allow interactions to
be fast, precise, extremely
compact, and low cost.
3. Sound Around Soundaround is a multi-viewer
interactive audio system,
designed to be integrated into
multi-view displays presenting
localized audio/video channels
with no need for glasses or
headphones.

1. Photocloud A near real-time system for
interactively exploring a
collectively captured moment
without explicit 3D
reconstruction.
2. Vision Blocks On-demand, in-browser,
customizable, computer-vision
application-building platform for
the masses. Without any prior
programming experience, users
can create and share computer
vision applications.

Strategy #3: X Do exactly the opposite
• Processing, Memory, Bandwidth
– In Computing world, in any era, one of this is a bottleneck
– But overtime, they change
– E.g. bandwidth is now considered virtually limitless
• Business Process Reengineering (BPR)
– Michael Hammer, James Champy, 1990s
• In imaging:
– SLR: Faster mirror flip or no mirror flip
• Companies spent years improving mirror flip speed
• Why not just remove it?
• More computation
• Less light

Strategy #4: X
• Given a Hammer ..
– Find all the nails
– Sometimes even screws and bolts
• Given a cool solution/technique/Opportunity
– Find other problems
– (Where to find them?)
• Examples
– Compressive sensing
– Mobile phone opportunity

Strategy #5: X
• Given a nail,
– Find all hammers
– Sometimes even screwdrivers/pliers may work
• Given a problem,
– Find other solutions
– (Where to find them?)
• Examples
– App store (Apple) ..
– How to create Open platform for all devices
– How to create a ‘hardware’ app store

Strategy #6: X++
• Pick your adjective ..
• Making it faster, better, cheaper
neXt = adjective + X

X++ : Add your favorite adjective
• Context aware,
• Adaptive
• (temporally) Coherent,
• Hierarchical,
• Progressive
• Efficient
• Parallelized
• Distributed
• Example: Image or video compression schemes
• Personalized/Customized
• Democratized

X++ : Add your favorite adjective
• Example: Image or video compression schemes
• But X++ is a sign
– The field is maturing in terms of research
– But booming in business impact
• Kaizen
– Small incremental changes
– Japanese Management styles (6sigma, Kanban)

Where to find the ‘X’
• Awards (best papers, product, researchers)
• Talks abstract
– no need to attend, subscribe to mailing lists
• Network and talk to people
• Avoid small-talk .. Ask ‘what is the latest X’
• Patents
• Table of Contents
• Index pages
![Page 55: Raskar Entrepreneurship in Imaging, Imaging Ventures, CVPR 2012](https://reader034.vdocuments.site/reader034/viewer/2022042723/53fc71498d7f723a2d8b4ecf/html5/thumbnails/55.jpg)
Ramesh Raskar, MIT Media Lab
Pitfalls
• These six ways are only a start
• They are a good mental exercise and will
allow you to train as a researcher
• Great for projects
• But
– Maynot produce radically new ideas
– Sometimes a danger of being labeled incremental
– Could be into ‘public domain ideas’

What are Bad ideas to pursue
• X then Y (then Z)
– X+Y is great with true fusion, fusion of dissimilar is best
– But avoid a ‘pipeline’ systems, where the output of one is
THEN channeled into the input of the next stage, and non
of the components are novel (idea is easy to scoop)

• Follow the hype (too much competition)
• Do because it can be done
– (Why do we climb a mountain? because it is there! )
– But only the first one gets a credit.
– May make you strong, and give you a sense of
achievement but not a research project.

– My personal triangle of criteria
• Fun, Impact, Money
• 2 out of 3
– Intersection of interests, skills, demand
– Maybe another talk ..
Is the idea worth pursuing?

Is project worthwhile? Heilmeier's Questions
• What – What are you trying to do? Articulate your objectives using absolutely no jargon.
• Related work – How is it done today, and what are the limits of current practice?
• Contribution – What's new in your approach and why do you think it will be successful?
• Motivation – Who cares?
– If you're successful, what difference will it make?
• Challenges – What are the risks and the payoffs?
– How much will it cost?
– How long will it take?
• Evaluation – What are the midterm and final "exams" to check for success?
• Why now? (why not before, what’s new that makes possible)
• Why us? (wrong answers: I am smart, I can work harder than others)

Great Research: Strive for Five
1. Before Five teams Be first, often let others do details
2. Beyond Five years What no one is thinking about
3. Within Five layers of ‘Human’ Impact Relevance
4. Beyond Five minutes of description Deep, iterative, participatory
5. Fusing Five+ Expertise Multi-disciplinary, proactive

Research ..
• http://raskar.info
– How to come up w ideas: Idea Hexagon
– How to write a paper
– How to give a talk
– Open research problems
– How to decide merit of a project
– How to attend a conference, brainstorm
– Facebook.com/ rRaskar
• Tips
– Get on Seminar/Talks mailing lists worldwide
– http://www.cs.virginia.edu/~robins/YouAndYourResearch.html
– Why do so few scientists make significant contributions and so many are forgotten in the long run?
– Highly recommended Hamming talk at Bell Labs

Unfair Advantage
![Page 64: Raskar Entrepreneurship in Imaging, Imaging Ventures, CVPR 2012](https://reader034.vdocuments.site/reader034/viewer/2022042723/53fc71498d7f723a2d8b4ecf/html5/thumbnails/64.jpg)
Extras ..
Prepare
• Internships
• Incubator (YC, TechStars)
• Move to cluster
• Find a mentor (but impress them first)
• If you do good stuff, good stuff will happen to you
• Journal paper, conf (get your ideas validated)
• Dont worry about discussing your plans w hundreds – Ideas don’t matter as much, team and execution matters
• Talk to people in very diff areas – (e.g. arial survey of powerlines)
• Should you have Prof. on board?
• Kickstarter (video demo)
•
Unfair Advantage
• Why now? (why not before, what’s new that makes possible)
• Why us? (wrong answers: I am smart, I can work harder than others)
IP
• Do asmuch in univ, file provisionals (talk to TLO)
• Why not to file – To enforce rather than defend (5 years, $3M)
– Prevent someone else from patenting (write journal paper instead)
– License (too much effort and luck)
• Why to file – Stimulate investment or acquisition
– Deter patent infringements lawsuits
– Have leverage wrt partners (before JV)
Productivity
• Biz Card
• Website
• CardMunch
• Use Google Doc for Exec Summary – (read only mode)
• Many online resources – biz plan, Founders Workbench (Goodwin Procter)
