Using Keyframe Selection to Improve Detection of Primate Faces in Videos

Poses of primates in video frames and their image quality are determined through image processing and machine learning. Frames with the highest quality and best pose are selected for further processing. Recognition of individuals was vastly improved.

Abstract (PDF)

I worked on this topic for my master's thesis to improve the detection rate of the SAISBECO project: Semi-Automated Audiovisual Species and Individual Identification System for Behavioral Ecological Research and Conservation.

Movie Tint

Exploring the colors of moving pictures.

I'm fascinated with colors in moving pictures, and started this project to visualize the colors and their change over time in films. It's quite hard to boil down all the information just one movie contains into a single image, but fun to play around with different and unique plots.

Objective-C Generics: checking type correctness at compile time for NSArray, NSDictionary and NSSet.

The language Objective-C doesn't provide generics. Heavily disputed whether they are needed in Objective-C, yet often used in comparable languages. WMGenericCollection provides generics for Objective-C through custom collection subclasses, which can be created with C Macros.

clHOG

For my bachelor's thesis, I implemented the Histograms of Oriented Gradients algorithm highly parallel for GPUs, with OpenCL. To speed up the calculations, I developed a new algorithm for the block computation and as a result surpassed several other implementation.

Visual Odometry

For an advanced seminar, I researched information on visual odometry. I was asked to rework my results into a set of slides, which were later used in the robot vision lecture at TU Ilmenau.

I love taking photos on my travels, at events and of people. In June 2013 I lead a group of international students for a week in Ilmenau at a student's festival, teching, learning and taking lots of photos. You can find a few of my photos on 500px.
