Rob’s geeky discoveries Blog

I got a mutiple face detection in Flash application running smoothly which is rather nice Thanks a million to Squidder and to the original author of the OpenCV file @ Intel, Rainer Lienhart. The deploy has  a zipped up XML document with Haar Classifier pattern recognition…

The AS3 unzips this data, grabs the blob/face detection data, polls frames from the camera and scans them for faces. When it finds them it will draw a rectangle around the detected faces and render them back on top of the video feed.

Check it out at http://bit.ly/HYkJF

A quick nose at the OpenCV Wikipedia stub will show you just how interesting this technology is as it’s used for:

• Ego-motion
• Face Recognition
• Gesture Recognition

FDT made knocking this together and sharing it on SVN in house at Glue a breeze. Hopefully I’ll knock something up with this and share some source other than what Squidder has already kindly posted.

Cheerio

There have been no posts from me for a while as I’ve been building the AS3 carousel section (eBay items) and a series of DoubleClick Ads utilising Twitter feeds in banners and Ebay listings in banners too.  The ads are in AS2 as the DoubleCick TABS system can’t yet take AS3 FYI (coming soon, Cheers Haden for the inside info!). This is all for The Sun Help for Heroes campaign where Ebayers can apply to become sellers and then donate their profits of the items they sell directly to the campaign. We’ve got loads of Celebrities to donate items too and there is a branded hub site pulling all this activity together live within eBay at:

In my rummagings on Cross Domain I discovered this good hack for accessing the pixels from Video on distributed CDN’s:

More posts soon hopefully although my day to day link posting is all being done via Twitter these days so follow along if you’re interested in these things. I am endeavouring to keep my microblogging professional rather than letting you know I am ‘on the bus’/'popped to the shop’ etc so Flash goodies are promised
