I was recently speaking with Ken Perlin regarding fast face tracking code. When he spoke of how his tracker matched on every frame using separate sums of horizontal and vertical pixels (compressed into columns and rows respectively), it reminded me of Integral Images in the Viola Jones algorithm.
I proceeded to enlighten the person who pioneered their use in computer graphics… Oops!
This is pretty incredible. If IBM figured out how to scale this a bit more, it could dominate the search industry.
Today I reversed engineered the core technology of a hardware company that recently raised a $20m+ Series B.
This just goes to show that keeping something secret doesn’t mean that others won’t be able to copy it or come up with something better.
The crazy thing is… I know next to nothing about hardware.
It was a depth sensor using a laser light source and an IR camera in a compact webcam-like enclosure. They made it sound magical, but it was really quite simple. They demoed it for about 15 minutes, and there were no pictures allowed. They shot down everyone’s guesses (structured light, time of flight, sonar), and didn’t really describe how the device worked. However, after a few minutes of thinking, extracting the trick behind the technology was pretty easy.
If their technology is really this simple, I’m guessing that their investors are actually investing in the business plan. Now I’m really interested in their strategy…
This video was quite enlightening. It does a good job of explaining how the economy drives us on a macro level.
I am suddenly interested in economics.
I didn’t know she spent 10 years traveling to research for this! Thanks for the link. The 20 minutes passed before I realized. Are you still interested in economics?
I really enjoyed this paper on microwaving vegetables vs. using other cooking methods. I also looked up the funding sources and it seems this paper is purely academically motivated rather than motivated by some microwave company.
The coolest finding was that some vegetables increased their antioxidative properties after cooking.

How long did it take you to figure it out?
You should see what kind of strategy they use so you can mold it for when you start raising money for your inventions.

After their demo ended, I guess it took about 15 – 30 minutes.
Their strategy is to be a component for product makers, who can claim the technology is theirs. I think they’re doing something like NVidia’s model, where they make a reference design and other companies can adapt it as they see fit.
