Computer Vision: IM520 Class Report (fall 2011/summer 2012)

This short post deals with contents, assignments and solutions of the (very cool) IM520 computer vision class by FH-Prof. DI Dr. Wilhelm Burger at the Campus Hagenberg of the University of Applied Sciences Upper Austria, which I attended from fall 2011 to summer 2012. I've delayed this post for quite a while now - so …

mctune: multicore hyperparameter tuning in R on the example of SVM car detection

mctune In Machine Learning (ML) tasks finding good hyperparameters for machine learning models is critical (hyperparameter optimization). In R there exist some packages containing routines doing that for you using grid search (constructing and testing all possible parameters as a grid, e.g. in David Meyer's e1071 package). Besides the very good routines already contained in …

Facedetection with JavaCV and different haarcascades on Android

The pan shot face recognition prototype from 2013 has been embedded in the prototypical face module of the mobilesec android authentication framework. The face module uses 2D frontal-only face detection and authentication, but additionally showcases pan shot face detection and authentication.
