Blob detection with Shearlets

The main research theme is to develop multi-scale methods for signal and image processing and to design efficient algorithms for signal enhancement and feature detection. The focus is both on the mathematical theory in the framework of non-commutative harmonic analysis and on the applications in 2D/3D image analysis.

About the theory we investigate the properties of signal representations associated with continuous frames parametrised by Lie groups, as for example the shearlet transform for 2D signals and its generalisation to higher dimensions. About the application we are interested in algorithms for feature extraction and description.
