Re: Methods To Sense The 3D Surface/Structure Of A Book

Here are a few more ideas: - Detection of book/page structure and content from pictures of the pages in motion. This is the essence of the book flipping-scanning proposal. http://singularityhub.com/2010/03/23/book-flipping-scanner-lets-you-record-200-pages-in-a-minute-video/ Although the prototype s...

Is there a Moore's law for camera resolution? I'm personally investing quite a bit of time into some other more optical/computationa...

I was hoping this would make for something portable and cheap, but in fact the resolution here would not be 1/2, but 1/4, of the resolution of standard two-camera DIY designs. First, half the resolution because you're ...

Re: Post something about yourself here (The Hello Thread)

Hi,

I'm a graduate student and research technician in Mexico City. (Almost finished that Ph.D... Arrrg!) I also have two very young daughters. I have an idea for a portable book scanner that I want to share. I'll post a summary in a new thread on the Hardware forum. Greetings!
