PRÜFUNG

Prüfungsdatum: 12.01.2016
Wiederholungsprüfung? nein
Note: 1.0 Bereiche nach Zeit: no clue

Fragensammlung: wie lauteten die Fragen im einzelnen?

Neuroinformatics;

Bayes, Modelvalidation, Modelselection, Basisfct (similar to other protocols)
You said that with AIC the parameters are punished, can we use this when the sample size is low? --> No, use AICc instead which also punishes sample size

Computer Vision (Sampling Theorem and Image Enhancement):

Tell me about the sampling theorem. --> Much blahblah
How to get rid of alias effects, example for alias effects in real life.
Asked how to get from normal space to frequency space --> Fourier

Tell me about Image Enhancement --> global and local contrast
If I have artifacts which are on certain pixels because of the camera or sth like that how do I get rid of them --> filtering with average
Average is ok, but for larger kernels it's not so good, what to take else --> median
What does the Median-filter do, why is this better? --> take the median gray value, also works good for larger kernels

Was mußte schriftlich gelöst werden?

Nothing in partiular, but I wrote down Bayes and draw pictures for the CV part

Persönlicher Kommmentar, Was war toll? Was war doof? Was war auffällig?

I got a coffee and Pipa was really nice.
