C/C++

Recently I acquired a Raspberry Pi 4 and decided to build a tiny computer cluster out of it. The goal is to do play around a bit with parallel computing technology. Some of the things that I will try out are MPI in Fortran Coarray Fortran Parallel computing with julia The Hardware The cluster consists of the following parts (see image above). 1 Raspberry 4 Model B (2GB) equipped with a 16GB MicroSD Card 1 Cluster HAT v2.

I develop a small toy setup with a pair of Arduinos and some ultrasound sensors to do object localization. The goal is to have at least 4 echo distances in each measurement to assert a unique solution of the localization equations. In addition to the position I also want to compute some validation criteria. The Hardware I’m using two Arduino Unos and 6 HC-SR04 ultrasonic sensors. Each Arduino is in control of 3 sensors and the sensors are placed in two rows of 3 sensors each (see below).

I’ve developed optimization algorithms for variational optical flow models based on the split Bregman algorithm in my Master thesis. A follow-up investigation on the necessity of certain intermediate filtering steps was published at the EMMCVPR 2011. I’ve also shown that the optical flow can be used in the context of partial differential equation based image compression. The results were presented in two publications at the SSVM 2019 and in the Journal of Mathematical Imaging and Vision.
