Hyperimages (part 2)

Monday, July 31st, 2006

Do you remember my post introducing hyperimages?
The process is on its way with PhotoSynth from Microsoft labs! Soon available, this application provides a wonderful set of new ways to explore images databases:

infinite and smooth zooming/dezooming capability on large sets of pictures (”Google Earth”-like)
automatic mosaics (panoramas) from multi-resolution pictures (with overlaps)
smart navigation through pictures: selection of […]

Automatic Photo Pop-up

Wednesday, July 26th, 2006

It’s a long time since I wanted to suggest browsing this page at Carnegie Mellon University. Derek Hoiem presents an automatic photo pop-up method based on segmentation of vertical, horizontal and sky objects in an image. The result is a 3D model allowing one to navigate inside the image!
His SIGGRAPH’05 article can be downloaded here. […]

Beijing (part 3): Elephant Memory

Monday, July 17th, 2006

Back from China, it was a very short trip!
I didn’t came back with a lot of pixels this time: only 166 723 584 pixels, I use to be better than that! I uploaded some pictures here (new entries in my previous Beijing gallery). It’s a good thing I might go there many times again in […]

3-D Desktop

Friday, July 7th, 2006

My couz’ (do not search in an english dictionnary, it isn’t even french…) is working on a 3-D desktop for Windows (XP), something like Xgl. I might not explain it clearly, the way it’s done is a projection of textures on 3-D objects (with DirectX rendering). Textures of course are windows contents. In order to […]

Free Space Display

Thursday, July 6th, 2006

A few days ago I have been talking about nano projectors. Trinn (he will open a blog soon, be ready…) just sent me a link to something you might have already seen. If not, look at this marvelous mid air video display from IO2 Technologies.

They are developing a display system using a rear projection of […]

HDTV: is it worth it?

Tuesday, July 4th, 2006

The question is: do we really need HD TVs?
Let\’s think about it in terms of visual acuity. The visual acuity relates to the smallest object we can distinguish from a given distance. For further details please go there or there (french). In this article we only deal with limit of separation between two points and […]

Nano Projector

Saturday, July 1st, 2006

Explay released its nano projector. Take a look at Gizmodo to find out what it is.
So, what is it? A system for projection of color pictures and videos from a portable device. The manufacturer says images are always well-focused and may have sizes ranging from 18 to 90cm. The device itself seems to be very […]
