Acoustic tomography for estimating temperature and wind flow

Martin Vetterli, Luciano Sbaiz, Ivana Jovanovic

We consider the problem of reconstructing superimposed temperature and wind flow fields from acoustic measurements. A new technique based solely on acoustic wave propagation is presented. In contrast to the usual straight ray assumption, a bent ray model i ...

Dynamic Texture Analysis and Synthesis using Tensor Decomposition

Luciano Sbaiz, Sabine Süsstrunk, Roberto Costantini

Dynamic textures are sequences of images showing temporal regularity, such as smoke, flames, flowing water, or moving grass. Despite being a multidimensional signal, existing models reshape the dynamic texture into a 2D signal for analysis. In this article ...

Head Related Transfer Functions Interpolation Considering Acoustics

Martin Vetterli, Luciano Sbaiz, Christof Faller, Thibaut Ajdler

We are proposing an interpolation technique for head related transfer functions (HRTFs). For deriving the algorithm we study the dual problem where sound is emitted from the listener’s ear and the generated sound field is recorded along a circular array of ...

Super-Resolution from Highly Undersampled Images

Martin Vetterli, Luciano Sbaiz, Sabine Süsstrunk, Patrick Vandewalle

Aliasing artifacts in images are visually very disturbing. Therefore, most imaging devices apply a low-pass filter before sampling. This removes all aliasing from the image, but it also creates a blurred image. Actually, all the image information above hal ...
