Today was a talk with Djoerd. It turns out that I still don't write enough. Experiments should get
noted down!

I started the feature extraction on trecvid 2005 data today to have a comparison.

With finding P(C|R) I unfortunately don't find the right settings back, which gave relatively good results. It seems that lemur implements the okapi method in a partical way (returns a document as early as possible). Therefore the score is not really acurate.

TRECVID

We signed up for the highlevel feature extraction task. For this Arjen contacted Christos from Greece who gave us binaries to extract wilbull features from jpg images. We extract these low level features now and will train (via cross valiadation) visual only models for the concepts. These models will be used to find the occurrence probabilities of the trainingsets of 2007 (and later 2008) data. With these we can make the results of the CIVR paper comparable between 2005 and 2007
