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.
