Call for party – CVPR 2010
Its a great honour to send you the call-for-party for the ************************************************************* * C'il Vous PaRty 2010 (CVPR'10) * *************************************************************
The main CVPR party is a selective party, with a 20-30% acceptance rate.
Party people in the main CVPR program must dress in high-quality, original outfits.
Dual submission to CVPR and any other party (gala, reception, premiere)is prohibited.
Topics of interest include all aspects of partying computer vision and pattern recognition including, but not limited to:
* Visual features for drink classification before exposure,
* Visual route planning (to the beer stack),
* Dance style preference ranking,
* Clique detection in parties,
* Learning applied to people matching techniques,
* Matching when there’s little to match: a case of computer vision party,
* How can max-flow help you in important stuff in life (like increasing the flow of beer through throat),
* Face identification in bad illumination and visibility (a.k.a. drunk) conditions, and
* Who TF put that on!? (Automatic DJ).
Furthermore, the CVPR is happy to announce two brand new challanges:
* UBB (“Unfinished beer bottles”) detector challange
* H2D2STC2W (“He’s too drunk to stand this close to window”) detector challange
Important date:
Saturday 13th of Novmeber, 21h
Honory Chair Alfred Heineken
Sharing is Caring Chair Oksana Yakhnenko
Drinking Chair Left in the corner
Music Chair David Guetta and DJ Tiesto
Organizing Committee Arnau, Josip, Thomas

Panaromas
The mountains are great, and the human eye is amazingly able to see panorama’s. Since I’ve a digital camera I often try to make a panorama. You make a series of pictures and use some software.
The software makes use of some nice computer vision / graphics algorithms and inventions to find keypoints in all photo’s, align the photo’s, rotate and translate the different pictures etc. Today I’ve used Hugin an open source implementation (although the famous SIFT descriptor which it uses is patented) to stitch the photos together.
But, since my new 12M pixel camera, I can also just take a picture and crop the image to see the panorama. Not good enough for poster printing, but much faster, always correct viewpoint etc etc. So here the comparison:
Panorama 1:
Panorama 2:
Now there are several questions which we could try to answer (may be see them as a unpaid HIT from AMT):
- Which one is created from a single image, and which one from 7 images
- Which one is better, and why?
- Can you see the image boundaries in the stitched one?
Artificial Artificial Intelligence
Now a days in computer vision (and may be in the broader range of computer science) we use a lot Amazon Mechanical Turk.
The name is based on the Automatic Chess Player designed in the 18th century:
The mechanism appeared to be able to play a strong game of chess against a human opponent. It was in fact a mechanical illusion that allowed a human chess master hiding inside to operate the machine. With a skilled operator, the Turk won most of the games played during its demonstrations around Europe and the Americas for nearly 84 years, playing and defeating many challengers including statesmen such as Napoleon Bonaparte and Benjamin Franklin. Although many had suspected the hidden human operator, the hoax was initially revealed only in the 1820s by the Londoner Robert Willis.1
Amazon created it to supply ‘Artificial Artificial Intelligence’, and we use it to annotate datasets. Given an image where is the head, body, etc:
The service (or tool) is already online for quite a while, and has been used for several task (eg: Finding Steve Fosset by analysing satellite images2, or making art based on 1000 drawn sheep (http://www.youtube.com/watch?v=3Mmb5aSscck), including a nice introduction into AMT).
Since we are using it soo much, I was wondering what it is ‘being a Turk’, what are the kind of questions asked etc. So I signed up for being a Turk. And played around a bit. Since the number of HITs (Human Intelligence Tasks) are overwhelming I focussed on a couple of ‘image’ related ones.
House cleaning
In my previous `colloc’ (shared flat) I complained a lot about 2 of my flatmates with a strange cleaning habit. Often when they came home at a Sunday evening around 9pm, within an hour the whole flat smelled like cleaning soda, because they cleaned (again) the hallway, the kitchen and the toilet…
It’s now 22:15 and I just finished cleaning the toilet, hallway and kitchen… And I wasn’t even away for the weekend… Today I spent most time home…
Giant Rapid
Finally I bought a new bike!! I planned it already for a while, but finally, finally I could decide which one I wanted. So now I’m the owner of a brand new Giant Rapid! I hope it will make me more rapid in the mountains.
Picture?!? Of course:
Today the weather was fine, but unfortunately the forecast for tomorrow and monday is less positive… Hopefully i can cycle a bit!

‘PhD’ – Birthday
Happy PhD-day to me
Happy phd-day to me
happy PhhhhD, happy PhhhhD
happy Phhhd-day to meeeee
(For a nice jazzy melody you should go to Alex’s Happy Birthday with Jazz feel)
Exactly a year ago I started my contract at Xerox, the official start of my PhD.
So, only two more years to go…
Via Ferrata
Today we went for the Via Ferrata of St Pierre d’Entremont. A village in the Chartreuse which is on the border of the Isere and the Savoie. (Last year I was there to hike around Cirque de St. Même). This year we sought in a different way the hight! A Via Ferrata is a perfect way of discovering climbing a long distance at high level above ground (200m?)
Thanks Rew for organising! And the weather couldn’t be better!
Besides, thanks to FNAC for my new camera, however some of these pictures are stolen from Rew and Hisako’s cameras!
Post Parcel
I was hoping to receive my new camera today, so I waited a bit at home. In order to open the door when the postman came. However at 11 I really needed to go to work…
Just as sanity check I opened our postbox expecting to find the note that I passed by but I wasn’t there…
And look what was inside:
Brilliant, they just open the postbox put the parcel there and leave!! And more important, I’ve my new camera before the weekend
