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 […]

The network is too slow No pixels then! But good food, very good food.

Tomorrow I go back to Beijing for work.
Lots of pixels to be discovered there, those for work (image processing) and those my digital camera will capture (go to my Beijing gallery to get an idea about this…).
Talk to you from there!

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 […]
