Research Interests
Technical Analysis of Financial Data
In the field of technical analysis I have developed many indicators and trading systems using a market model based on the harmonic superposition principle of waves similar to the linear system models of electrical engineering. For a deeper understanding I have developed different algorithms for the spectral analysis of financial data. One analyzer is based on the MESA algorithm of Dr. John Parker Burg, another analyzer is based on the Goertzel algorithm of the discrete Fourier transformation of Dr. Gerald Goertzel and a third analyzer uses autocorrelation (folding of price data phase-shifted with itself).Feature Engineering for Robotics
Developing feature engineering algorithms for Artificial Intelligence (AI) of robots is another research topic. For the RoboCup I have developed image processing and computer vision algorithms for the Standard Platform League together with the HTWK University Leipzig. Currently I have started a new robot vision project based on a Raspberry Pi computer with a HD camera module. The Raspberry offers a full featured linux platform, which supports many programming languages, and has more computing power than a NAO robot of the RoboCup at the fraction of the price, which is ideal for pupils, students and universities. The topics of the current algorithms include:- play ground recognition using color calibrations,
- field recognition using edge detection,
- goal post recognition,
- ball recognition and
- self localization.
