DPAP photo sharing in f-spot

Today I have commited the initial code of the mono addin utilizing the dpap-sharp library I'm working on during this year's GSoC.
It's finally in a state where I can post a screenshot to show how the shared photos from f-spot show up in iPhoto (currently only up to 5.0 - newer version are not supported yet), so here is...

gnome-randr-applet

Just finished a little dirty hack to make gnome-randr-applet more useful. It's now possible to turn outputs on and off as with xrandr --output XXX --auto and xrandr --output XXX --off with a single click. I find it very handy. Screenshot below.


The patch is for version 0.4.1 of grandr, which is available from the author

Santa's here, late bastard.

A little trip back in time, just in time. For those of you that dare, there's a recompiled version of the TabBrowse extension for OpenOffice.org, now working with the current 2.3.0 branch! You can fetch it here (Unix version only right now, sorry). That's the same thing that came out as a product of my SoC05 endeavour with OO.o, but compiled against the current 2.3.0 office. It won't blow your mind, but hey, more is on the way!

As to face detection - running the training on an extensive set of examples and features turned out to be more time consuming then expected. Selecting the first! feature takes a brief 24h :-) hopefully the training will conclude this year...

My masters thesis is still blank, but stuff's starting to clarify in my head as work on the code advances (and it does).

Sunday

Done some research regarding my masters thesis. Seems that I'll make a pretty good use of the lecture slides provided by Marc Pollefeys of UNC Chapel Hill, especially his Multiple View Geometry course (http://www.cs.unc.edu/~marc/mvg/), I'm also in process of acquiring a book by Hartley & Zisserman "Multiple View Geometry in Computer Vision" and "Computer Vision - A Modern approach" by Ponce. Those, along with a bunch of papers, should cover most of the 2D->3D stuff I'm going to do in my thesis.

F-spot - I looked into the Adaboost algorithm of my trainer, seems that it concludes the training too fast (after 4-5 stages), I remember I was happy with that earlier, because I got some results, but the training only took a couple of hours, but now it's time to make it work it's way up to 20-30 stages, like in the original V-J classifier.

I bought a dsm-g600 NAS device a couple of months back, today I'll be trying to put uShare onto it so it will uPnP stream my photos / music / videos to my home network. Maybe a cool idea for f-spot - adding a dpap plugin, so it could pop-up a photo library just like rhythmbox does with music libraries.

Follow-up

Wow, it's been 4 months since I last blogged. Time flies - seems to be my keyword for life. For the past couple of days I've been thinking about how to improve the results of my face detection implementation and I think the order's gonna be (I'll stick to Viola-Jone's nomenclature, if something's not clear to you please check their paper) :
1. Switch to integral images and integral-image-based features
2. Fix AdaBoost (there's something wrong with my AB implementation, it's not optimal - gotta find why

After that I should run the training process on a larger dataset and see how it affected the results.

During my stay in Tucson, over the summer, I've been doing some work at the University of Arizona, namely at the Arizona Simulation Technology and Education Center - ASTEC. Because of my interest in medicine I'm very happy of the time spent in that lab, I was also able to collect some data that should make a basis for my thesis - "Image processing in computer-guided surgical training". One of the interesting things I'll be doing in there is a structure-to-motion application. My website http://wytyczak.com/andrzej/upload/ should have the most up-to-date stuff on that matter.

SVN, rev 21

As of SVN rev 21 I consider the project ready. Lots of fixes and improvements have to be made for this to be really usable, but that's going to be apart (like me ;)) of the Summer of Code program.
The schedule was heavily modified due to some caught exceptions - I'm leaving to the U.S. for a scholarship at the University of Arizona on wednesday and because of legal restrictions had to finish SoC before that time. I therefore claim that done and anyone from IRS reading this may note that no more paid work will be done by me for this years SoC ;)

Now I'm diving into my suitcases! Have fun at guadec everyone!
