"description":"In this talk we discuss recovery guarantees for the reconstruction of wavelet coefficients from Walsh measurements, which appear in fluorescence microscopy, lensless cameras and other analogue measurement advices with an “on-off” behaviour. We consider both linear and non-linear reconstruction methods. For the analysis we discuss the typical structure of signals under the wavelet transform and the properties of the change of basis matrix. The results offer a guideline on the choice of sampling pattern and an insight to the relationship between Walsh functions and wavelets.",

In this talk we discuss recovery guarantees for the reconstruction of wavelet coefficients from Walsh measurements, which appear in fluorescence microscopy, lensless cameras and other analogue measurement advices with an “on-off” behaviour. We consider both linear and non-linear reconstruction methods. For the analysis we discuss the typical structure of signals under the wavelet transform and the properties of the change of basis matrix. The results offer a guideline on the choice of sampling pattern and an insight to the relationship between Walsh functions and wavelets.
