n.V.Research
I have been working in the field of screen content coding since November 2020. The current focus is on probability modeling for arithmetic coding by exploiting the specific charactersitics of screen content data.
Offered Theses
I offer student theses in the field of screen content coding at any time. Basic knowledge of MATLAB, Python or C++, and image and video signal processing is desirable.
If you are interested, feel free to contact me via email with a short description of your previous experience in software developement and image and video signal processing (e.g. lectures, internships, laboratories, own projects, etc.).
