Learning Antenna Pointing Correction in Operations: Efficient Calibration of a Black Box
Leif Bergerhoff
We propose an efficient offline pointing calibration method for operational antenna systems which does not require any downtime. Our approach minimizes the calibration effort and e…
Seeing the World through an Antenna's Eye: Reception Quality Visualization Using Incomplete Technical Signal Information
Leif Bergerhoff
We come up with a novel application for image analysis methods in the context of direction dependent signal characteristics. For this purpose, we describe an inpainting approach ad…
Stable Backward Diffusion Models that Minimise Convex Energies
Leif Bergerhoff, Marcelo Cárdenas, Joachim Weickert +1
The inverse problem of backward diffusion is known to be ill-posed and highly unstable. Backward diffusion processes appear naturally in image enhancement and deblurring applicatio…
Algorithms for Piecewise Constant Signal Approximations
Leif Bergerhoff, Joachim Weickert, Yehuda Dar
We consider the problem of finding optimal piecewise constant approximations of one-dimensional signals. These approximations should consist of a specified number of segments (samp…
