I came back home less than half an hour ago. I was out for dinner (sushi) with a friend that I haven’t seen in a long time. He came to Japan for a short vacation. Arrived today and already saw a few interesting things. Like, for example, drunken youngsters barfing in the train station 8)
Of one scene he took a picture. Hopefully I’ll get that picture ! Two girls and one guy, one girl collapsed on the floor. Her friends ready with plastic bags. Another, scene with a guy holding up his friend as he barfed on his own and the friend’s shoes. Cool !

As far as the Aibo goes. This weekend I didn’t spent much time on it. I did manage to get to change the JPEG quality parameter, of course it was my mistake. That’s a big step forward. Next I need to buy some sort of piece of material large enough to use to take reference shots to individuate the camera static noise. I did some research and I found out that the idea of using this method to cope with the typical CMOS cameras noise is already out there.. therefore it’s feasible. Now I’m just not sure what should be a reference material. Possibly something that diffuses light well (definitely not specular). Maybe it would be best if I had three panels, one red, one blue and one green, to take three different reference shots to apply to the three separate color components of the incoming images. I’m not sure how well this would work though, because I will be processing JPEG images, which have the color space being transformed from RGB to YUV and then back to RGB. All these operations would be best performed on the original raw data.

Onto the webcamera thing over at dpasca.homeip.net ..I decided to revive my old webcamera applet used for webkaz. Because the cross fade is a pretty nice feature and also because I suspect that with the current system (reloading images using JavaScript), Firefox leaks memory. I don’t quite have the proof though.
Also I’ve been thinking of reviewing Java applets coding. Because it’s the only way to have enough freedom to do things that will run on a browser. And to involve people in experiencing things, it’s much easier to ask them to tune their browser somewhere, rather than install a software that will rely on a custom connection, with eventual firewalls getting pissed and false warnings of spyware.. a currently very delicate issue !
